Electronic Tattoo-Like Devices Monitor Brain, Heart and Muscles [VIDEO]

We might one day be able to monitor our bodies' internal functions -- and prevent things like epileptic seizures before they happen -- using a flexible circuit attached to the surface of skin. The National Science Foundation announced Monday that researchers are working on a prototype tattoo-like device that can detect heart, muscle and brain activity.

Tiny curly wires in a flexible membrane make up these devices and work better than conventional hard, brittle circuits, because body tissue itself is soft and pliable.

"We're trying to bridge that gap, from silicon, wafer-based electronics to biological, 'tissue-like' electronics, to really blur the distinction between electronics and the body," said materials scientist John Rogers from the University of Illinois Urbana-Champaign. "As the skin moves and deforms, the circuit can follow those deformations in a completely noninvasive way."

These devices could detect brainwave activity before a seizure and respond to the electrical abnormalities. The scientists also say the could be particularly useful for premature babies.

"They are such tiny humans that this epidermal form of electronics could really be valuable in the monitoring of these babies in a manner that is completely noninvasive and mechanically 'invisible'," Rogers said.
