Abstract
A piezoelectric acoustic resonator based sensor is presented herein. A device can include an array of piezoelectric transducers and an array of cavities that has been attached to the array of piezoelectric transducers to form an array of resonators. A resonator of the array of resonators can be associated with a first frequency response corresponding to a first determination that the resonator has been touched, and a second frequency response corresponding to a second determination that the resonator has not been touched. The array of piezoelectric transducers can include a piezoelectric material; a first set of electrodes that has been formed a first side of the piezoelectric material; and a second set of electrodes that has been formed on second side of the piezoelectric material.
