Two Research Groups Create 'Electric Skin' 52
Flash Modin writes "Two separate teams, one from UC Berkeley and the other from Stanford, have created distinct types of artificial skin that could find uses in prosthetics or artificial intelligence (Data in First Contact, anyone?). The first team coupled organic electronics with an elastic polymer to make electric skin that could sense a butterfly landing on it (abstract). The second team put a flexible material over a conductive rubber compound which had transistors implanted in it. The device can sense touch when the rubber is compressed, changing the electrical resistance (abstract)."
Use with prosthetics (Score:3, Insightful)
I guess everyone's first thought will be that they can use this with prosthetics so someone with a fake limb can actually feel. But, I don't see mention of how this could possibly connect to human nerves. Is that kind of thing even possible?
On a separate note, it would probably be annoying considering many prosthetics these days are still really crappy. Until we have a true cyborg limb that can respond to nerve signals, and indeed respond with this fake skin's input, it seems kind of useless. Maybe there's another use I'm missing?

My first thought was that this was resistive based touch technology -- that's sooo last year! And surely skin must be one of the best applications for multi-touch.

Not only possible but fairly trivial. You don't have to tie directly into the nervous system, you can use the electrical signal to stimulate another patch of skin, and the brain will quickly learn to interpret the signal properly. But it is also possible (but less trivial) to tie directly into the nervous system - this is done on a regular basis with cochlear implants, and there are a few experimental retinal implants now too.

Also, if they couldn't properly connect it to the nervous system, the patch of skin it stimulates could be on the same arm, maybe under where the prosthesis fits. It may be my elbow feeling the tingle, but after a while, I will adapt to recognize that tingle as being somewhere on the back of my fake hand.

If I remember correctly, prosthetics connecting directly to nerves pop up in the news from time to time. There's an article from SingularityHub on something like this. here it is. [singularityhub.com]
That fake limb in the article can feel, it has no skin though. So maybe now that there is electric skin we can put them together and get a cyborg arm.

Robotics.
It's been a while since I designed any robots, but there is a big problem with robots in general in that unless you explicitly design sensors to detect something, it won't.
I can't get into the applications here (there are just too many) but having the ability to feel objects not perfectly lined up with the robot's programmed path could help prevent a lot of injuries.
Imagine a robot with this skin wrapped around it, as it moves, it comes into contact with something that it shouldn't have (Some guy), it immediately can stop that motion and hopefully just bruise the guy instead of just continuing mindlessly and slicing the guys arm off or crushing him to death.
That's just an off the top guess, but I would also very much like a robotic grasping arm that could sense pressure. It's easy to design something to grasp, and maybe even put in some resistance (ie: hooke's law), but getting a feel for the force it exerts and the exact positioning of that force could be very useful.
Imagine a grasping arm that doesn't need to be perfectly aligned with an object and could react to the thing it was grasping (ie: reducing the movement of one 'finger' if it felt the object slipping) being able to compensate for a misaligned object could be very useful.

This is something which is already done with some current prosthetic limbs. Nerve endings from severed limbs are surgically transplanted to convenient mounting locations [youtube.com]. Simple pressure-sensitive structures on the surface of the prosthetic fingers then transmit a signal to the contacting device on the other end of the artificial limb, which in turn, transfer that data to the transplanted nerve ending, by applying equivalent pressure. The prosthetic device is stimulating the same nerves that the original hand did, so the user experiences the sensation as though he still had it, with no need to re-learn signal patterns. Some cutting-edge prosthetics can also pick up nerve signals, and move at the command of the mind, rather than requiring the user to do something more awkward, such as wearing a pressure-sensitive insole in his shoe, and adjusting his balance, every time he wants to lift a spoon to his mouth.

I think that was his point -- that in some ways we've surpassed what Star Trek's writers could imagine just a short time ago. Like Star Trek II when McCoy couldn't cure Kirk's age related presbyopia; all he would have had to do would be transport Kirk's lenses out of his eyes, and transport a CrystaLens in its place.
I have one in my left eye (although they used a needle to remove/replace, of course). It not only cured my steroid-induced cataract, it cured my extreme myopia and my age-related presbyopia. If I'd had astigmatism it would have cured that too. I'm 58 and don't have to wear any corrective lenses at all after wearing thick glasses all my life.
But Star Trek's writers couldn't envision a focusable artificial lens, and had Kirk wearing reading glasses.

It is also sometimes a 'gift' to the actor. A lot of times the actor DOES have a problem that we don't have a current solution for but the 'future' world likely would. Rather than punish the actor by having them attempt to do a scene without glasses, or expect them to not suffer from arthritis, they will write in either some impediment to what we would expect the cure to be, or write in a new diseas

I'm sure that's true in a lot of cases, but an actor on the soundstage doesn't need reading glasses because he's not really reading. It makes no difference if he can actually see the book; the book is just a prop.
