Abstract: A fingerprint sensor for incorporation into a smart card includes sensor electrodes for detecting fingerprint features of a finger placed on a contact surface, the sensor electrodes being disposed above a substrate layer that comprises a first portion, a second portion, and a ledge where an edge of the first portion extends beyond an edge of the second portion. Contact points disposed on the ledge connect the fingerprint sensor to electrical conductors of an intermediate layer of a multi-layer smartcard. The fingerprint sensor is disposed within a cavity formed in a body of the smartcard, and the contact points disposed on the ledge are set at a depth corresponding to the thickness of an outer layer covering the electrical conductors of the intermediate layer of the smartcard.

Abstract: An electronic sensor forms a grid to detect surface features of a proximally located object, such as a fingerprint. The grid includes a plurality of parallel drive lines connectable to a drive source and a plurality of parallel pickup lines oriented substantially perpendicular to the drive lines and overlapping the drive lines. The drive lines are separated from the pickup lines by an insulating dielectric layer. The overlaps where the drive lines and pickup lines cross define impedance-sensitive electrode pairs which act as pixels at which surface features of the proximally located object are detected. One or more conductive probes extend from one or more corresponding impedance-sensitive electrode pairs, through an overlay layer of insulating material, to the sensing surface.
