New Electronic Sensors Stick To Skin As Temporary Tattoos

Researchers have created a new thin flexible sensor that can be applied with water, like a temporary tattoo. Measuring activity in the brain, heart and muscles, the innovation could cut down on the number of wires and cables medical personnel use to monitor patients, among other applications.

The electronics can bend, stretch and squeeze along with human skin, and maintain contact by relying on “van der Waals interactions” — the natural stickiness credited for geckoes’ ability to cling to surfaces.

In addition to being designed with a hardy serpentine pattern that resists tearing, the sensors are thinner than a human hair.
