Tiny Robots Powered by Living Muscle Cells
voma writes "Tiny robots powered by living muscle have been created by scientists at the University of California, Los Angeles.
The devices were formed by "growing" rat cells on microscopic silicon chips, the researchers report in the journal Nature Materials.
Less than a millimetre long, the miniscule robots can move themselves without any external source of power. Muscles like these could be used in a host of microscopic devices - even to drive miniature electrical generators to power computer chips."
but still... pretty crazy what scientists can do. I won't say EVIL EVIL! or YAY PROGRESS! I mean, we are human. we will dabble. these things will be invented. just hope like so many other inventions, the good outweighs the bad.

besides. 1mm of rat muscle? man. how puny

Say that again after looking at Steve ballmer perform.
Since we have now redefined nanotech to include anything that deals in nanometer scale structures, rather than artificially constructed mechanisms with molecules as components, how far back in time can we claim "nanotech" to have been practiced? The first crystal growth? Perhaps to the first time a crystal was cleaved along certain atomic planes?
Perhaps we could do something similar with "space settlement" and just sort of forget that 1973 was the year that western civilization turned away from its destiny in space and began threatning the planet with globalist growth.
That should make everyone feel better too.

Can devices like this potentially use chemicals in blood to generate mechanical energy and then electricity so as to replace pacemakers? It'd be nice if those things had indefinite battery life rather than what they have now, what, 9 years?
Of course, I'm surprised that you couldn't just do a mechanical generator for that. Or have they?

The abstract from the paper
Current procedures for manual extraction of mature muscle tissue in micromechanical structures are time consuming and can damage the living components. To overcome these limitations, we have devised a new system for assembling muscle-powered microdevices based on judicious manipulations of materials phases and interfaces. In this system, individual cells grow and self-assemble into muscle bundles that are integrated with micromechanical structures and can be controllably released to enable free movement. Having realized such an assembly with cardiomyocytes we demonstrate two potential applications: a force transducer able to characterize in situ the mechanical properties of muscle and a self-assembled hybrid (biotic/abiotic) microdevice that moves as a consequence of collective cooperative contraction of muscle bundles. Because the fabrication of silicon microdevices is independent of the subsequent assembly of muscle cells, this system is highly versatile and may lead to the integration of cells and tissues with a variety of other microstructures.
"even to drive miniature electrical generators to power computer chips."
This makes it seem as if muscle cells can act as a source of free power. I'm sure the above plan would work, but only for a very short time... Just as human beings can run "without an external power source," until we need to recharge (i.e. eat). We use sugars to produce ATP which gives us the energy we need. But the problem is that our bodies contain all of the necessary facilities to convert sugar into ATP quickly and efficiently, while lone muscle cells on a computer chip do not. They would eventually be forced either to remove the cells and replace them with new ones, or to find a way of recharging the cells, which sounds like a project in itself.
* Olaserov is in the process of thinking up a signature.
Why is the word "growing" in quotes in the posted article? Did the scientists not actually grow the muscles?
Muscles would be great replacements for all sorts of electrically powered motors/servos out there. There's a lot of chemical energy stored in organic material, so switching over to artificial muscle based machines would virtually solve the battery problem faced in so many disciplines right now. Batteries are heavy, don't really store that much energy, and require toxic chemical considerations both in their manufacture and disposal. Artificial muscle on the other hand can extract very easily the energy contained within common foods/organic paste and only create waste by-products that have less impact on the environment because they're biodegradable. :)

They think we don't see it, but this is just another piece in the puzzle. Yes it's all begining to make sense.
The cybernetic rats are taking over. And they're pissed. Angered by the years of experiments, they have already taken over the scientists, and they are using them to take over all our technology. It's only a matter of time now...

The cells DO need a source of power: ATP. That's our input. The desired output is electrical energy. 1. ATP 2. -> mechanical energy 3. -> electrical energy I admit, the cool factor is there, but why can't we just use chemical reactions to extract the raw energy from ATP's chemical bonds?

I suppose if it gets sick you'll have to take care of it rather than just order a new set of power supply "muscles" from newegg.
"As the owner of an organic power supply system, you are bound by state and federal regulations which require you to provide the correct operating environment for your power supply. Because your power supply is a biologically engineered device, it is sensitive to its environment; as such your power supply's operating environment must be free from all known cancer causing chemical agents and other problem components. Failure to provide the proper operating environment will void your warranty and may violate GMO rights laws in your area (CA, CO, MN)

I would rather see giant robots powered by whale muscles.
Now we are starting to create organic and machine hybrids. Cyborgs are going to be the eventual evolution of this. If you can do it molecularly its only a matter of time before we do it on a life size robot.
The actin-myosin fibers in the muscle run on ATP, but the muscle cell generates this itself. The fuel used by the cell is carbohydrates and fats, which is turned into energy (ATP) for the fibers and other processes. The energy-generating process can be either anaerobic (fermentation) or aerobic (respiration). For more information, look here.

A lot of people complain that this is playing god but household dust is mainly just dead skin cells. Does that make the grooves between the keys on my laptop the killing fields? Nope. People say our brains are wet machines. I think we should change perspective. Machines have been "wet" for billions of years and we come along and make some robots and religions and add an adjective to label the norm. But then how would we label a non biological sentient robot with a drinking problem? Extra dry?

A young adult generates 1/2 watt per pound of body weight sitting, and four times that in exercise. Thats why they have to air condition auditoriums even in the winter with hundreds of those "light bulbs" sitting there.

Rat muscle is patented by God himself, meaning that any use of rat muscle in manmade devices may be defended against in court. However, don't despair. For just $699 per cell, you, too, can harness the power of biology in your applications with GODX's BioRobot Liscence! Without such a liscence, you are violating God's intellectual property rights, and doesn't that just make you feel plain guilty? And if it doesn't, well, there's always litigation and, well, that eternal hellfire thing.

Now we can rate systems in MHz and Horsepower.
No, these robots use muscles that need energy, just like your heart. They don't generate electricity from blood, but there was a story in August 2003, Powered by Blood: "Bringing us one step closer to becoming centrally-controlled meatbots, Japanese scientists have developed a device that produces power from the glucose in human blood." If they combine both of those technologies we might have meat robots powerd by blood, which would be the first step in creating life. The question is: should we play God? Could we create a monster? Do we have a right to do it? Those are very serious questions that have to be answered before any mass production begins because otherwise we might destroy the morality as we know it, if not the life itself.

I've always wondered why scientists couldn't put an array of millions of mitochondria on a chip and use that as a fuel cell. Mitochondria are extremely efficient at extracting energy aerobically from glucose (something like 31 ATP molecules from one molecule of glucose). Why not just strip the extra baggage and employ mitochondria directly?

Sure making cars or other objects that extracted energy from ATP's bond would be possible, but this way we could create perhaps a chip that could be implanted inside your body and would be powered soley from your muscle cells.
