sensor invented that uses radio waves to detect subtle changes in pressure

10 octubre 2014

A new sensor has been developed by engineers that is made of a special rubber layer between two strips of copper that act like radio antennas; the rubber is an insulator. Pressure squeezes the antennas infinitesimally closer, altering the electrical characteristics of the device. Radio waves beamed through the device change frequency as pressure changes, providing a way to gauge pressure wirelessly. The underlying technology could lead to prosthetic devices with an electronic sense of touch.
