Device for capturing signatures uses tiny LEDs created with piezo-phototronic effect

August 11, 2013

Piezo-phototronic LEDs2 Georgia Tech researchers want to put your signature up in lights. Using thousands of nanometer-scale wires, the researchers have developed a sensor device that converts mechanical pressure--from a signature or a fingerprint--directly into light signals that can be captured and processed optically.
