  • Fingerprint sensor with impedance detection
    Patent number: 11328536
    Abstract: A fingerprint detection device comprising a support having a bearing surface, a sensor arranged to capture an image of a dermatoglyph of a user's finger placed on the bearing surface, and an impedance-measuring electronic circuit connected to electrodes extending on the bearing surface, conductive tracks extending on the bearing surface between the electrodes and the impedance-measuring electronic circuit. At least two of the electrodes are connected to the impedance-measuring electronic circuit by at least two conductive tracks.
    Type: Grant
