New alternative to RFID chips: Electronic Skin

'Electronic skin' could be used to heal wounds

A tiny, wireless patch of "electronic skin" could one day be used to monitor a patient's vital signs like temperature and heart rate and help heal wounds.

Eliminating the bulky wiring and electrodes used in current monitors would make the devices more comfortable for patients, according to an international team of researchers who reported their findings in the journal Science.

"What we are trying to do here is to really reshape and redefine electronics ... to look a lot more like the human body, in this case the surface layers of the skin," said John A. Rogers of the University of Illinois. "The goal is really to blur the distinction between electronics and biological tissue."

The researchers embedded electronic sensors in a film thinner than the diameter of a human hair, which was placed on a polyester backing like those used for the temporary tattoos popular with children. The result was a sensor that was flexible enough to move with the skin and would adhere without adhesives.

The researchers said the devices had remained in place for up to 24 hours. Mr Rogers said while normal shedding of skin cells would eventually cause the monitors to come off, he thought they could remain in place as long as two weeks.

In addition to monitoring patients in hospitals, other uses for the devices could include monitoring brain waves, muscle movement, sensing the larynx for speech, emitting heat to help heal wounds and perhaps even being made touch sensitive and placed on artificial limbs, Mr Rogers said.

Yep. to them we are animals. its especially creepy since it feels like your skin, and they can easily put on people, even without them being knowledgeable about it. But the whole "monitoring brain waves, muscle movement, sensing the larynx for speech" is the creepiest to me.

That is just creepy. It reminds me of being tagged like an animal.
