Battery-Free Wearable Patch Can Help Monitor Health

A battery-free electronic patch that sticks onto skin like a temporary tattoo can be powered wirelessly by smartphones to help monitor health, researchers say.

Now researchers have developed a stretchable, wearable ultra-thin device that can not only wireless transmit health data, but also is wirelessly powered via near-field communication transmissions. Smartphones, tablets and other consumer electronics use near-field communications with the Apple Pay and Android Pay wireless payment schemes.
The battery-free nature of this patch makes it five to 10 times thinner than comparable gadgets, says study leader John Rogers, a materials scientist at the University of Illinois at Urbana-Champaign.
