Abstract: Microelectromechanical systems (MEMS) electret acoustic sensors or microphones, devices, systems, and methods are described. Exemplary embodiments employ electret comprising an inorganic dielectric material such as silicon nitride in MEMS electret acoustic sensors or microphones. Provided implementations include variations in electret acoustic sensor or microphone configuration and recharging of the electret.

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.

Abstract: A method, system, and apparatus magnetically coupled electrostatically shiftable memory device and method are disclosed. In one embodiment, a method includes electrostatically decoupling a separate structure and a surface that are magnetically coupled (e.g., an electrostatic force to decouple the separate structure and the surface is generated with an electrode), shifting the separate structure between the surface and a other surface with the electrostatic force (e.g., shifting the separate structure moves the entire separate structure), and magnetically coupling the separate structure to the other surface.
