Electric Fork Simulates a Salty Flavor By Shocking Your Tongue (med.news.am)

An anonymous reader writes: It's common knowledge that excess sodium can be detrimental to one's health. So researchers in Japan have built a prototype electric fork that uses electrical stimulation to stimulate the taste of salt. The battery-powered fork was engineered and designed at the University of Tokyo's Rekimoto Lab. It features a conductive handle that completes a circuit when the tines make contact with a diner's tongue, electrically stimulating their taste buds. The prototype fork, which was built from just $18 worth of electronics, creates a sensation of both salty and sour, and has adjustable levels of stimulation.

      You don't even have to ask. Just use some common sense.

      Start with the fresh produce department, where the bulk of what you should be eating should be coming from anyway.

      Rice of all sorts, quinoa, wheat, oats and other grains are also readily available and contain none of the things you listed, so you can get some variety in your carbohydrates if you're tired of potatoes and yams.

      For protein, most stores will have at least half a dozen different types of dried beans. If you don't want to eat a vegetarian diet, it's not hard to find meat and eggs produced without growth hormones, antibiotics and so forth.

      In other words, the only reason you're stuck with all the stuff you've listed in your food is because you're choosing to buy products that contain all that stuff. Buy the ingredients and cook your own food and you get to choose what goes into it.

Beef is aged, albeit usually not long enough. Pork is about the least processed food you will find. Everything else has had something done to it.

      The problem is that most of these additives are actually not at all dangerous to people either short or long term. It's the health food industry that wants you to be scared of it but just like homeopathy which you'll find in the same isles there is no evidence to it. Yes, lots of HFCS will cause diabetes but so will the raw cane sugar in similar amounts. A lot of these "additives" are equally found in vegetables and fruits occurring naturally, anyone who is scared of sugar-replacers like aspartame should never eat strawberries that have aspartame in much higher dosages. Red food colorings are oh-so unnatural ground up beetles or beet juice.

The reason - to continue collecting old-age pension checks. This typically occurred in the more rural mountain communities leading to the assumption that a rural mountain life was a healthy one. Turns out this is not true. And now that the government is aware of the problem it gets abused far less and the statistics are being corrected.

    I suspect that you could squeeze enough energy into that volume to electrocute someone; but humans are reasonably resistive(even if you accidentally stabbed yourself with the fork, it looks like there is an electrical contact on the handle, so it has to pass at least one layer of skin), so unless some sort of insane enthusiasm for liability led them to design the thing to deliver fairly high voltage at at least moderately punchy current, it would still be harmless.

    It doesn't actually take much energy, at all, to kick some unlucky sucker's heart into a life threatening abnormal state; but you have to deliver that very modest jolt to the correct place; and doing that is a matter of either nontrivial brute force or very bad luck.

    Full Definition of electrocute
            transitive verb
          1 : to execute (a criminal) by electricity
          2 : to kill by electric shock

    Notice that the definition of electrocute involves dying? When you say "mild electrocution", you're saying "mildly dead", which doesn't really make a lot of sense.

    You're welcome to use the word as you want, of course (that's one of the fundamental things that makes English a living language) but when someone else is using the word, you need to be aware of the dictionary meaning of the word or communication suffers.

    That having been said, electricity takes the path of least resistance. The only way the path between the tines of the fork will be through your heart or the nerves that drive your heart will be if the fork has been stabbed into your heart or your spine or, I suppose, just the right bit of your brain. In all three cases, you have much bigger and more lethal problems than the minuscule amount of current between the tines of the fork.

      The links between salt consumption and disease is only apparent in a small number of people that seem to have some sensitivity to salt.
      These people have an underlying condition(s) that has remained un-diagnosed for decades because of a horribly flawed STUDY (one, ONE!) that was never re-tested until recently, where it was ripped apart.

      Yet there are people that go nuts over even minor amounts of salt that it is almost likely the stress and anxiety OVER salt itself that is causing the high blood pressure. (it isn't entirely the case though)
      This device will certainly help some people out with intolerance to it, at least until they figure out the root cause of it. (which could just be salt, there are people with intolerances to water on skin!)

    To kill someone using electricity you need to deliver certain amounts of energy in a short time (think Coulombs not Volts/Amps). There is also a range for which it works, too little and nothing happens, too much and you're just clamping someone's heart after which they likely recover (although you could've caused severe burn and internal organ damage).

    You could potentially kill someone based off a battery based device but you need to modify the signal quite a bit.

    Look up super capacitors.

    Argh! Supercapacitors are special because of their resistance to leakage and a high energy density. They actually have a lower voltage so they discharge slower, are heavier AND more expensive than regular electrolytic or ceramic capacitors making them exactly the WRONG choice for the purpose of electrocuting someone based on every possible consideration. What you want is an electrolytic capacitor in series with the power supply and a pull-up resistor set in parallel with the resistor going to ground. Go back to the eighth grade you AC retard!
