‘Tattoo’ sensor reads body’s health

AN electronic “stick-on tattoo” has been developed that can be worn almost invisibly while measuring valuable information from the heart, brain and muscles.

The ultra-thin patch, flatter than the diameter of a human hair, is packed with sophisticated electronics including tiny sensors, light-emitting diodes, transmitters and receivers.

All the components are integrated onto a polyester backing similar to those employed in stick-on tattoos.
