Peltier Junction

[Enigma_Man]

These work using a peltier junction. For those not "in-the-know", peltier junctions are basically chunks of metal that push heat to one side when you run current through them one way, and the other side when you run current through them the other way. This provides a cold, and a hot side that can be varied very quickly from cold to hot, by changing the amount and direction of the current. They are very inefficient though, requiring a lot of current that is generated as excess heat overall. These are commonly used to cool processor cores down, pushing more heat into the heatsink, but keeping the core cooler than it would be with just a heatsink.

Re:Peltier Junction

[RapmasterT]

These are commonly used to cool processor cores down, pushing more heat into the heatsink, but keeping the core cooler than it would be with just a heatsink.

I'd disagree that they're "commonly used" for CPU cooling. Peltier heat sink assemblies have fallen way out of vogue in the last few years and were never particularly popular in the first place. Problems like generating a significantly higher amount of waste heat, while simultaneously creating a frost (no kidding) and condensation problem made them extremely impractical when faced with water cooling options.

That being said, peltier cooling IS commonly used in those little desk top refridgerators and portable DC cooler/warmers that you see for sale in RV catalogs.

Re:Peltier Junction

[ZephyrXero]

I've actually often wondered what it would take to give a synthetic sense of touch to something. I'm guessing this "peltier junction" must be the best option for temperature since that's what their using? What else would you need, and how would you accomplish it? You would need the ability to feel whether or not something is hard or soft, whether or not it is rough or smooth, and that's really about it? Could both smoothness and hardness be deteched by the same sensors? If anyone knows please reply...it's fasinating :)

Re:Peltier Junction

[Enigma_Man]

Peltier junctions are most often used for CPU cooling, I suppose is what I meant to say, though that was just a guess. I've also seen them in those port-o-coolers too... Anybody know of anything else these are used for?

-Jesse

Re:Peltier Junction

[Enigma_Man]

Well, in this article, it says that the nerves from the guy's hand were reattached into his chest, attached to a pneumatic plunger that would push on the nerves when his replacement hand was pushed on; that would give him the sense of touch/pressure, though I doubt it has the resolution for something like surface texture. I'm assuming in this case (it's how it's done elsewhere in prosthetics) that there are also peltier junctions touching the nerves to provide the hot/cold sensation. In the past, the peltier junction was connected to the stump of the arm, so that you would be able to feel hot or cold, but it wouldn't actually feel like it was on your previous hand, it'd still feel like it was on the stump.

-Jesse

Re:Peltier Junction

[RapmasterT]

Sharper Image used to sell a neck cooling thing that used peltier coolers, but then they changed it to a water evaporator design. Battery life probably sucked on the original.

Re:Peltier Junction

[ZephyrXero]

Well, I not only wonder about it in the sense of prosthetic replacements, but what about for a full out robot? Or I guess more in my field, what about in a virtual world on an AI creature...

On the topic of heat/cold again...couldn't they put a bunch of tiny thermometors (sp?) embedded in a synthetic skin and then have a chip give the brain the appropriate sensations based on that data?

Re:Peltier Junction

[Enigma_Man]

That's essentially what they're doing here. They're using temperature-sensors in the fingers of the robotic hand, and then using peltier junctions directly connected to the nerve endings from the old hand that relay that temperature to the brain.

It'd be nice if we had direct interfaces into the brain, but we don't yet.

-Jesse

Re:Peltier Junction

they're also used for precision temperature control.

Re:Peltier Junction

[cr0sh]

These work using a Peltier junction. For those not "in-the-know", Peltier junctions are basically chunks of metal that push heat to one side when you run current through them one way, and the other side when you run current through them the other way.

Umm - not exactly. What you are describing is commonly known as a TEC, or "Thermoelectric Cooler" (and also known as a Peltier cooler). They are not composed of a single Peltier junction, but rather a large multitude of such junctions in what is basically a semiconductor package. A TEC is basically a semiconductor-based heat pump, which uses electricity to move heat from one side of the TEC to the other. In the process, the TEC also generates a fair amount of heat (no such thing as a "free lunch") from the hot side, while also consuming a fair amount of energy (which most of it is converted to heat, the rest moving heat from the cold side to the hot side). Finally, remember that you can't generate cold - coldness is the absence of heat.

Now, as I have noted, TECs work via the use of multiple Peltier junctions. Peltier junctions are fairly simple devices, consisting of a junction made between two dissimilar conductors. TECs are made in this manner, but in the same way as ICs are made (more or less). On a larger scale, though, a Peltier junction is easy to make - get a piece of alluminum wire, and a piece of copper wire, and twist them together: congratulations, you have just made a simple (though very inefficient) Peltier junction (however, this is not what can cause house fires in older homes with alluminum wiring - this problem is caused by a combination of alluminum and copper wire junctions heating up because of the resistance of the junction, thus starting a fire).

Peltier junctions work by using something known as the Peltier Effect, which was observed in 1834 by Jean Peltier 13 years after the Seebeck effect was first discovered. The Seeback effect is basically the inverse of the Peltier effect - in that two disimilar conductors, in the presence of a heat source, generate an electrical current. This effect has been used in industry to detect and measure extremely high temperatures, such as what is generated in various industrial furnaces. It has also been experimented with as a method to use the sun to generate electricity (ie, use a solar furnace to focus the sun on a bundle of the junctions) - there is actually an old Popular Mechanics article from the 1950's or 1960's showing how to build such a device.

As to whether you can use a TEC to exploit the Seebeck effect in a practical manner - probably not, as they aren't designed to work in this manner, and you might destroy the device. However, these devices are cheap enough, and if you supplied an appropriate cooling system for the device you might get a bit of electricity out of it - just don't expect much. It would make an interesting science fair project for the kids, though (grab a TEC, a fresnel lens, and a very large heat sink with a fan, bolt it all together and hook it up to a cheap voltmeter, then set it in the sun).

BTW - where did all the real geeks on this site go to, anyhow?

Re:Peltier Junction

[Enigma_Man]

Uh, no... I was describing a peltier junction, as in one single solitary junction. A peltier junction is a chunk of metal (I simplified, hence my use of the word "basically", it's actually a chunk of _two_ metals, excuse me) that pushes heat to one side or another depending on which way you shove current through them... Which is also exactly the way you described them, and exactly what I described... I'm missing the part where I was wrong.

-Jesse

Re:Peltier Junction

[cr0sh]

First off, I never said you were completely wrong - I merely implied that your statement was off a bit, and that I wanted to expand upon it to provide readers with a deeper understanding of just what a Peltier junction was. Your original statement (first sentence, actually) was:

These work using a peltier junction.

Most explicitly the use of the word "a" - had you stated something akin to "These work using a multitude of peltier junctions", I would be more inclined to uphold your statement on the whole. I still would have expanded upon it, just dropping my first sentence in the process.

A Peltier junction is just that - a junction between two dissimilar electrical conductors - which for most purposes are metals, but doesn't necessarily have to be. They aren't a single chunk, nor two chunks, but instead a "bonded" junction - in a macro-size Seebeck junction (which, remember, is just a Peltier running in reverse), the bond is typically a brazed bond, or in some cases just the wire is twisted tightly together (a mechanical bond). I suppose even an epoxied bond could be used for a lower temperature probe...

Finally - my last sentence was mostly a plea for more in-depth comments to be made. Yes, what you described was technically mostly correct, but told nothing about how such a device actually works, nor does it give any history of it. I guess I expect on a site supposedly filled with geeks some comments which can educate. A simple link on the words "peltier junction" to a site similar (or the same) as what I linked would have been perfect. Please don't argue "just use google", because while one could, that is really a cop out to avoid doing the work of providing links in a medium and forum explicitly designed for them. We should strive, where we can (as needed by context, and to the commentor's knowledge), supply the links, not expect people to look it up on their own - because most won't, and many of the rest won't know how to search properly (thus possibly finding incorrect explanations)...

Old, artificial arm joke

[winkydink]

This reminds me of the old joke about the voice-actuated artificial arm.

They finally attach one to an armless human patient and it goes like this.

The guy says, "Arm, scratch my nose". And the arm does it.

"Amazing!", says the guy.

"Arm, sign my name." The arm does it.

This continues for quite a while. Finally when the guy's alone.
He says, "Arm, take off my pants." The arm complies.

He looks at the arm, and then at his penis and says, "OK arm, jerk it off!"

So then the next logical step is that he gets a prosthetic, voice-controlled penis, right? What's so wrong about that? Back in my youth I would get erections all the time in public. A fine lady would walk by, and my flagpole would stand at attention! But now with a voice controlled penis this man could say, "Down, boy! Down! Down!" and his penis would go flimsy.

I suppose it could slow the research of growing artificial limbs, but I would personally hope to see mechanical limbs as a sort of "loaner" until your new biological limb can be grown (much like you would borrow a car from a dealership when your car is being fixed). More so, I would posit that growing limbs is much further down the line than mechanical limbs. The two streams of research will probably continue unabated by the other for quite some time to come.

Re:What does this mean to biotechnology?

Skeletal reconstruction associated with a third arm, not to mention the control issues (is it even possible?) would make replacement far more likely than augmentation.

Some people, yes. Some people, no.

It probably won't take us long to make an arm that in some ways exceeds the capabilities of real arms. Your first thought is strength, but a strong arm requires a strong body to support it. But you might embed other things in it that Nature hasn't seen fit to provide us, or at least have an arm that is strong without having to be exercised.

But it will likely be a while before we have an arm that is a uniform improvement over our real arms. Healing, for instance, is a really nice feature, it is just loaded with sensors, and it integrates well with the rest of the body without much extra effort.

If your arms were removed and made stronger and impervious to pain your body would also loose that much cooling capacity and also muscle tissue to burn off all those pizzas.

Arms are easy anyway, try making a leg that does that. Your leg makes thousands of muscle changes a second to keep you upright. Your arm just hangs there by comparison.

Re:What does this mean to biotechnology?

[Jerf]

It depends on the situation.

If I live in a city, and I'm willing to bet my arms that society will not collapse so far that I can't get my arms fixed, it may be a good tradeoff.

On the other hand, if for some reason I will not or can not depend on a technological society to back me up indefinately, I may choose to keep my conventional arms, which will, most likely, continue working effectively indefinitely, until the rest of me is dead. (There are several caveats in that "most likely".)

A lot of people have criticized the human body in the past, but to date, it's the best known thing for living on planet Earth across the span of technology from effectively none to at least slightly beyond where we are now. We may be able to beat human arms in the case of high technology, but it's an open question IMHO whether we can create a replacement arm that is significantly better and different (i.e., not just a tweaking of what we have) that could still be a pure advantage even in the event of some society-smashing catastrophe.

Robotic arms - or better yet, a full body, General Grievous-style - would be really useful in a lot of ways. You could race motorcycles or work with heavy machinery without worrying as much about getting killed or spending months recovering from a serious injury.

If they had standard connections, you could even swap out various types depending on the task. Playing the piano? Switch to the hands with fingers twice the length that an un-augmented human has.

Progress

[Bimo_Dude]

They're making progress in this ares, but still have a long way to go. I wonder how long it will take for the researchers to develop some kind of motor system that is lightweight and has enough tourque to more accurately mimic normal human movements.

This may also advance the general robotics fields too (I would love to have a robot to fetch food and clean).

Prosthetic brain?

[Anonymous Coward]

From Article:

A lineman for a Tennessee power company, Sullivan in 2001 grabbed a high-tension wire carrying 7,400 volts of electricity, which incinerated his arms.

I don't mean to sound like an insentive asshole (but I probably will anyway) but don't you think he has bigger problems if he's grabbing high voltage power lines?

Was this one of those famous, "Hold my beer and watch this!" situations that seem to have become so well known?

Re:Prosthetic brain?

[Darth_brooks]

More like one of those instants where your brain, while processing the signals you've just sent to your appendages, says to itself:

Fuck. This guy's an idiot.

I've done stupid things with electricty. Similar things. Not once, but twice, I've touched both metal ends of a Flourescent light tube while the light was on. Once while a box cutter was in my hand, touching the metal end of one of the lights. Not me showing off being an idiot, just having one of those beautiful moments where Darwin should have taken over. My hands got moving faster than my mind could slow them down.

This guy was probably up on a cherry picker. His weight shifted, a gust of wind came along, etc and as he started to fall his insticts yelled:

GRAB SOMETHING!

meanwhile his mind, not really paying attention sees what's happening and says:

Nono don't grab th.....nevermind.

Yeah, the guy probably screwed up somewhere down the line but Shit will invariably, consistently, and always, Happen.

Re:Prosthetic brain?

[Linker3000]

Where I did my electronics engineering apprenticeship, we had a guy who had suffered a similar accident. His whole nervous system was shot to pieces and he had to wear tinted glasses because his eyes became sensitive to light. He had two claws for arms...and worked as a draughtsman in the drawing office!

One day he was in front of me at a drinks vending machine and he asked me to put the coins in for him as this was about the only thing he couldn't do with his claws. He punched the buttons and out came a cup of coffee. Just as he went to pick it up, the plastic 'splash door' on the front of the cup area (which was stuck up) came down and knocked the cup, spilling coffee over his claw.

"Damn", he said, "but at least I didn't get burned!".

He was a really nice guy.

Re:Prosthetic brain?

[Bill Wong]

Parent is modded funny, but, this is exactly what happened to the guy.
Nowadays, instead of using a 'cherry picker' to do work on high-voltage lines, a helicopter and a harness is generally used, as helicopters tend to be more mobile and quicker... (and, as a side benefit, this method avoids this exact problem.)

Here's an article with a little more details on the technical end:

Rewired, amputee lifts arm with mind

Relocated arm nerves

[nizo]

Sullivan's prosthesis has a computer in the forearm that is wired to a mechanical hand and to a "plunger" device on his chest. The hand sends signals up the wires to the plunger, which pushes the skin. That stimulates the nerves in his chest to transmit sensations to the brain as if the nerves were still connected to his real hand.
On Wednesday, when Kuiken touched a spot on Sullivan's chest, Sullivan said: "Oh, that's right between the finger and thumb on the back side of the hand."
If Kuiken touches one of Sullivan's prosthetic fingers, Sullivan can feel it and say which finger it is.

Wow. I just know he is glad he can still play the "pull my finger" game with his grandkids.

LISTER grunts, effort twisting his feature as the hand lies motionless

KRYTEN: That's right, sir, now keep going, now *really think*, now. Hand, pick up the ball! Now let's really get it going, sir!

LISTER: Pick up the ball! *Pick up the ball*!

KRYTEN: REALLY START TO GO NOW, SIR!

LISTER: HAND, PICK UP THE BALL

KRYTEN: NOW LET'S KEEP MOVING! KEEP ON, SIR, YOU *CAN* DO IT!

LISTER: HAND, PICK UP THE BALL!

KRYTEN: YOU'RE GOING TO MOVE THAT HAND, SIR! YOU'RE *GOING* TO MOVE IT! MOVE THE HAND, SIR!! LISTER: HAND! PICK UP THE BALL!! PICK UP THE BALL!!

KRYTEN: YES SIR! YES! WE'RE STARTING TO MOVE, NOW! YES! IT'S DEFINITELY MOVING, SIR! YES!! Oh! Bravo, sir!!

Feedback is an important breakthrough

[Weaselmancer]

Two way communication with the prosthetic is a huge breakthrough! Glad to see this is becoming possible.

Without this kind of feedback, control becomes...very difficult. For example, think of the cruise control in a car. You can make a decent one with a pair of opamps. The (oversimplified) way it works is that it takes the speed you're going and finds the difference between that and the speed you'd like to be going and uses that difference to work out how much to push in your accelerator.

Now try to work out how to do one if you're not allowed to know how fast the car is already going. Cut the two way communication, and it becomes much harder to do.

Resistance is Futile!

No, he was right. They are tapping into the nerves. Your brain will react just as if it were a real arm.

If it's hot, you would yank your fake arm back involuntary, if it is really to hot you'd feel the pain and drop what you were holding. Your central nervous system will never adjust to the loss of a limb.

Long distance feeling

If you can have an artificial sensation, there is no requirement that it be something local that you're feeling.

You'd still have to deal with the speed of light issues, but I guess four one hundredths of a second (for the diameter of the earth) wouldn't be too noticiable.

There's a fair amount of stuff that can be voice-activated these days (the Mac I'm writing this on has a lot on it by default) so I imagine that depending on what he wanted to do on the computer, he might be able to go that route.

Check out ocular tracking devices AND use voice recognition. There are some ocular (eye) tracking devices out there, but I don't know of any that are commercially available. Essentially an ocular tracking device follows eye movement to control the mouse, blinking is translated into clicks. Voice recognition is getting quite good on current hardware for both the Windows and OS X. Do some Googling on the ocular thing - I saw something on TLC/Disc/(insert cable spam channel here) about a kid that was paralyzed from the neck down using one to communicate and use a comp.

[mangu]

Was this one of those famous, "Hold my beer and watch this!" situations that seem to have become so well known?

Most probably not. There was a similar case in an electric power company where I used to work years ago. This is how it happened: A maintenance crew was doing a job in a 180MW generator in a power plant. While an engineer was holding simultaneously the 13800 volts busbar, with a short-circuit current of 20000 amps, with one hand and the grounded rack with the other hand, someone closed the breaker. The engineer's arms were instantly carbonized, he died three days later.

This accident wasn't caused by stupidity, but by bad coordination. After this, the company instituted a security measure to avoid it happening again. The breaker controls in all power stations were fitted with a protecting bar with several holes matching a stud in the panel. Everyone working in the generator puts a padlock through one of the hole pairs, and keeps the key. The breaker can be closed again only after every padlock has been removed.

Re:Accidents happen, you insensitive clod!

[Anonymous Coward]

This accident wasn't caused by stupidity, but by bad coordination.

This specific incident may not have been caused by stupidity, but the absence of the type of safeguards that were installed after the fact comes closer to qualifying. I'm certainly glad to hear that they wised up and started doing things right.

I don't know how many years ago you're talking about, but these days, lock out/tag out is an OSHA requirement. I'm happy to say that people at my plant have been fired for not doing it right. Your story is a great example of why it should be taken seriously.

It just has inputs and outputs (sense/nerves) and then tries to figure out how they are useful to do somthing useful. I also think that's the way a baby learns using his body. The only difference is that we already have all the neurons pretty much trained/connected for a specific purpose (controlling our body), so changing will take more time.

Ned Quinn stood back, wiped his hands, and admired the huge bank of dials, light and switches. Several years and many fortunes had gone into this project. Finally it was ready.

Ned placed the metal skullcap on his head and plugged the wires into the control panel. He turned the switch to ON and spoke:

"Pound Note."

There was a whirring sound. In the Receiver a piece of paper appeared. Ned inspected it. Real.

"Martini", he said.

A whirring sound. A puddle formed in the Receiver. Ned cursed silently. He had a lot to learn.

"A bottle of beer", he said.

The whirring sound was followed by the appearance of the familiar brown bottle. Ned tasted the contents and grinned.

Chuckling, he experimented further.

Ned enlarged the Receiver and prepared for his greatest experiment. He switched on the Materialiser, took a deep breath and said,

"Girl."

The whirring sound swelled and faded. In the Receiver stood a lovely girl. She was naked. Ned had not asked for clothing. She had freckles, a brace and pigtails. She was eight years old.

"Hell!" Said Quinn.

Whirr

The fireman found two charred skeletons in the smouldering rubble.

Takes the fun out of...

[VolcomPimp]

I thought half the fun of having a prosthetic limb was giving yourself a stranger?

Nerves sensing

[SeanDuggan]

I can't answer from a biomedical engineering standpoint, but from a physiological standpoint, the nerves in your skin detect only two things, heat and pressure. Everything else is interpretation of those.

Really, there is no subject in here, although Slashdot requires me to put one in...

Support Issues

[SeanDuggan]

As haphazard as bodily construction sometimes seems to us (Why build a recreational area next door to a waste dump?), there is a reason for the existing skeletal and muscular structure. You need a lot of support to properly manipulate your limbs. What do you plan on attaching this third arm to? Planning to build another shoulder joint? Create new shoulder blades? A new clavicle attached lower on the spine? Where are the muscles going to go and to what will they attach? By the time you finish adding an extra arm, I suspect you will have practically rebuilt the torso.

Och... and don't even get me into the sci-fi phenomena of the guy with a bionic arm being able to easily heft tons. The rest of the body can't support that kind of weight, let alone the sheer problem with the immediate point of connection between the bionic and organic parts.

"... let alone the sheer problem with... "

from dictionary.com: complete and without restriction or qualification; "got the job through sheer persistence";

from Hibbeler, "Mechanics of Materials": The sheer force lies in the plain of the area and is developed when external loads tend to cause two segments of the body to slide over one another.

Now that's a clever pun.

The Technology Advance

[SeanDuggan]

As I understand it, this case is notable for a handful (no pun intended) of reasons:

1. This guy lost his arms up to the shoulder. Most nerve-sensing prosthetic arms rely on the bicep and tricep muscles, as it is not feasible to directly interface the nerves with the equipment as of this time. In this case, they were able to reroute the nerves to another seemingly unrelated muscle group in the chest.
2. The nerve part of the process is obviously getting better.
3. The amount of feedback he's getting from this arm's sensors is orders of magnitude greater than what was available before.

A good deal of this is simply better technology, everything from lighter materials to using a computer to sort out signals. *shrug* No, it's not revolutionary, but it is evolutionary and the goal of making a replacement arm as good as a real one looks like it may be coming into sight.

Material and practical limitations

[SeanDuggan]

First of all, aren't robbers people? If you prick them, do they not bleed? But enough sniping...

There are some structural limitations for partial replacements. An extra-strong grip wouldn't be that difficult, as all of the mechanics are located in the wrist and hand area. Something like lifting a heavy weight, though, and not only your arm is bearing the strain, but so is the shoulder (or whereever you attach the things) and the rest of the body. It would probably be more likely that you rip an artifical arm out of the socket trying than to actually rip apart the safe.

The other general issue with mechanical amplification is the lack of feedback. Look at the discussions of exoskeletons and you'll find that it's not as easy as multiplying the force or speed of a motion. On the other hand, with the neural feedback they're getting with this guy, it may yet be possible to solve the feedback problem.

Re:Material and practical limitations

[Mechcozmo]

Having no feedback in some situations may be a good thing... like if the hand was crushed under debris. So if you could turn off the feedback, it could possibly be a benefit and a detriment.

Circumstances of Accident

[SeanDuggan]

Two of the articles linked say that he accidentally touched a live wire with both arms. One has said that he was repairing a transformer when lightning struck it. *shrug* Doing electrical work when lightning is in the area isn't exactly the brightest move either, but I'm sure you, like most people, curse every minute that a blown transformer deprives you of power and people on life support probably like it even less.
