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.

Finger biometric sensor including laterally adjacent piezoelectric transducer layer and associated methods

An electronic device includes a portable housing, an optical source carried by the portable housing, and an optical dispersion finger sensor carried by the portable housing. The sensor may include an integrated circuit substrate adjacent the optical source so that light propagates into and is dispersed by the user's finger with at least a portion of the dispersed light exiting the user's finger in a direction toward the integrated circuit substrate. The sensor may also include at least one optical dispersion sensing pixel on the substrate for sensing dispersed light from the user's finger to be used to generate optical dispersion biometric data from the user's finger. A processor may be connected to the one or more sensing pixels to enable at least one device function based upon the optical dispersion biometric data.
