Prosthetic Skin with Touch Sensing
December 9, 2014 | Terry Sharrer
Stanford University engineers have developed a wireless pressure sensor that’s small enough to sit on the tip of Franklin Roosevelt’s nose, as shown on the dime. The sensor has a “sandwich” design of silicon end pieces, with two layers of copper coils separated by a rubber insulator. In the presence of a radio frequency beam, pressure exerted on the sensor changes the emitted frequency into a sense of touch. In due course, this may create a prosthetic hand’s touch with these sensors on each finger, but perhaps more immediately they could be used for detecting blood pressure or cranial pressure.
