Claim:
1. A biometric object image sensor comprising: a plurality of capacitive gap sensor electrode traces formed on a glass substrate, wherein the plurality of capacitive gap sensor electrode traces form an array of biometric sensor imaging pixel locations within a biometric sensing area of the biometric image sensor, wherein at least one of the capacitive gap sensor electrode traces comprises a transmitter electrode trace and at least one of the capacitive gap sensor electrode traces comprises a receiver electrode trace, wherein a change in a resulting signal received by the receiver electrode trace is indicative of a biometric image characteristic at a respective pixel location in the array of biometric sensor imaging pixel locations; and a controller integrated circuit (IC) mounted to the glass substrate, wherein the controller IC is in electrical contact with the plurality of capacitive gap sensor electrode traces.
