Abstract: An acoustic imaging system coupled to an acoustic imaging medium to define an imaging surface. The acoustic imaging system includes an array of piezoelectric acoustic transducers formed at least in part from a thin-film piezoelectric material, such as PVDF. The array is coupled to the acoustic imaging medium opposite the imaging surface and formed using a thin-film manufacturing process over an application-specific integrated circuit that, in turn, is configured to leverage the array of piezoelectric actuators to generate an image of an object at least partially wetting to the imaging surface.

Abstract: A finger biometric sensing device may include drive circuitry capable of generating a drive signal and an array of finger biometric sensing pixel electrodes cooperating with the drive circuitry and capable of generating a detected signal based upon placement of a finger adjacent the array of finger biometric sensing pixel electrodes. The detected signal may include a relatively large drive signal component and a relatively small sense signal component superimposed thereon. The finger biometric sensing device may also include a gain stage coupled to the array of finger biometric sensing pixel electrodes, and drive signal nulling circuitry coupled to the gain stage capable of reducing the relatively large drive signal component from the detected signal.

Abstract: An electronic device may include a finger biometric sensor that includes an array of electric field sensing pixels and image data output circuitry coupled thereto and capable of outputting image data from a plurality of sub-arrays of the array of electric field sensing pixels and processing circuitry coupled to the image data output circuitry. The processing circuitry is capable of determining movement of a user's finger across the array of electric field sensing pixels by comparing image data from borders of adjacent sub-arrays, the movement causing artifacts in the image data, and, when movement of the user's finger is determined, remove the artifacts from the image data.
