Fingerprint scanner

3-D fingerprintA new ultrasonic sensor raises the security standard of fingerprint sensor technology currently used on smartphones and other devices. Developed by the Berkeley Sensor & Actuator Center, co-directed by Bernhard Boser, professor of electrical engineering and computer sciences, it makes the image of the fingerprint three-dimensional, eliminating the risk of counterfeited two-dimensional images. The new sensor pictures the ridges and valleys of the fingerprint’s surface, as well as the tissue beneath.
