1. An apparatus comprising: an imaging sensor including an array of pixels, the pixels arranged in rows and columns and each of the pixels comprising a capacitance transducer that includes a receiver electrode and a dielectric layer; wherein a first surface of the dielectric layer directly contacts the receiver electrode; a second surface of the dielectric layer, opposite to the first surface, is configured to be coupled with an object to be imaged; the receiver electrode is operatively coupled with a TFT amplifier input and defines a first plate of the capacitance transducer; the object to be imaged, when coupled with the dielectric layer, defines a second plate of the capacitance transducer; and a voltage of each capacitance transducer is sensitive to a distance between the first plate and a proximal portion of a surface of the object to be imaged.
