Abstract: A finger biometric sensor may include a finger biometric sensing layer having an upper major surface and at least one sidewall surface adjacent thereto. The finger biometric layer may be for generating signals related to at least one biometric characteristic of the user's finger when positioned adjacent the first major surface. The finger biometric sensor may also include a piezoelectric transducer layer coupled to the at least one sidewall surface of the finger biometric sensing layer and a plurality of electrically conductive layers coupled to the piezoelectric transducer layer to define transducer electrodes. At least one of the electrically conductive layers may also cooperate with the finger biometric sensing layer for sensing the at least one biometric characteristic.
