摘要： Tunable MEMS resonators having adjustable resonance frequency and capable of handling large signals are described. In one exemplary design, a tunable MEMS resonator includes (i) a first part having a cavity and a post and (ii) a second part mated to the first part and including a movable layer located under the post. Each part may be covered with a metal layer on the surface facing the other part. The movable plate may be mechanically moved by a DC voltage to vary the resonance frequency of the MEMS resonator. The cavity may have a rectangular or circular shape and may be empty or filled with a dielectric material. The post may be positioned in the middle of the cavity. The movable plate may be attached to the second part (i) via an anchor and operated as a cantilever or (ii) via two anchors and operated as a bridge.

The microelectromechanical filter includes an input electrode, an output electrode, one or several piezoelectric resonators, one or several high quality factor resonators, and one or several coupling beams. The input electrode and the output electrode are disposed on the piezoelectric resonators. The high quality factor resonator is silicon or of piezoelectric materials, and there is no metal electrode on top of the resonator.

摘要： An electromechanical filter capable of attaining a size reduction and a higher integration and executing a high-sensitivity signal sensing is provided. A quantum device is used as a sensing portion to implement a fine and highly sensitive sensing. A microvibrator 101 that is able to resonate with an input signal, and a sensing electrode 103 arranged at a predetermined interval to the microvibrator are provided. Since a change in an electrostatic capacity between the microvibrator and the sensing electrode can be sensed, a high-sensitivity sensing mechanism that is hard to realize in the prior art can be achieved.
