Title
(EN) ULTRASOUND FINGERPRINT DETECTION AND RELATED APPARATUS AND METHODS
(FR) DÉTECTION D'EMPREINTES DIGITALES PAR ULTRASONS, ET APPAREILS ET PROCÉDÉ ASSOCIÉS
Abstract
(EN)
An ultrasound fingerprint sensor is described. The ultrasound fingerprint sensor may incorporate capacitive ultrasound sensing technology, for example in the form of an array of capacitive ultrasonic transducers. The ultrasound fingerprint sensor may be incorporated into various electronic equipment, such as mobile electronic equipment in the form of smartphones and tablet computers, as well as in biometric sensing equipment, such as fingerprint access terminals.
