Biometric image sensing

Abstract:

A novel sensor is provided having a plurality of substantially parallel drive lines configured to transmit a signal into a surface of a proximally located object and also a plurality of substantially parallel pickup lines oriented proximate the drive lines and electrically separated from the drive lines to form intrinsic electrode pairs that are impedance sensitive at each of the drive and pickup proximal locations. A switch is integrated with the sensor.
