Next Generation: Electronic Skin

THE DEVICE: The epidermal electronic system (EES) is flexible, thinner than a human hair, and applied to the skin like a fake tattoo. Depending on the embedded circuitry, it can monitor body temperature, brain activity, or the contraction of the heart and skeletal muscles, and power tiny LEDs, transistors, or antennae for communications. It draws energy from its micro-scale solar collectors or wireless inductive coils, making it lightweight with no external power cords.

WHAT’S NEW:Traditional devices for sleep or heart monitoring include battery packs wired to large, inflexible sensors. This makes the units heavy, cumbersome, and a source of skin irritation. To create a chip that is as pliant as skin, John Rogers, an engineering professor at the University of Illinois at Urbana-Champaign, and colleagues created squiggly-shaped conductive gallium arsenide wires and mounted them on silicon that is less than 7 micrometers thick—two orders of magnitude thinner than a typical 500 micrometer silicon chip.More Details -Click here
