Abstract
A fingerprint sensor and fingerprint sensor system especially for integration in a device having an overlay made of an insulating material comprises a plurality of sensing elements positioned on a first side of the overlay; a plurality of probes positioned in a predetermined pattern defining a fingerprint sensing area on a second side of the overlay, the plurality of probes extending from the first side of the overlay at least partially through the overlay; a plurality of conductor leads on the first side of the overlay interconnecting the plurality of probes with the plurality of sensing elements; a plurality of amplifiers connected to the plurality of sensing elements, the number of amplifiers being less than the number of sensing elements; and an activation circuit connected to the plurality of sensing elements, the activation circuit being adapted to output at least one activation signal.
