Abstract
Some embodiments provide a sensor element, a shield element capacitively coupled to the sensor element and to ground, a coupling circuit to receive an input signal, and to electrically couple the received input signal to the sensor element and to the shield element, an output circuit to generate an output signal, the output signal based on a capacitance between the sensor element and an object, and a classifier to determine a material based on the output signal, and to transmit a material signal to the output circuit based on the determined material, wherein the output circuit is adjustable based on the material signal.
