摘要： The invention is a system incorporating a self-tuning resonator and method of self-tuning a resonator within a system. In one embodiment, a method of powering a system with energy harvested from a vibrating surface includes receiving a first mechanical energy at a first driving frequency from the vibrating surface, transferring the received first mechanical energy to a suspended structure within the system, vibrating the suspended structure with the transferred first mechanical energy, passively adjusting the resonant frequency of the suspended structure to a first resonant frequency associated with the first driving frequency by moving a movable mass in response to the movement of the suspended structure, vibrating the adjusted suspended structure with the transferred first mechanical energy, generating electrical energy using the vibrations of the adjusted suspended structure, and powering the system with the generated electrical energy.

摘要： A system and method are provided which includes ring resonator structures coupled together with beam structure(s). The ring resonators are configured to operate in the contour or breathe mode. The center of the coupling beam structure is used as a nodal anchor point for anchoring the ring resonators and the beam structures, and also provides a reflecting interface. In an embodiment, the coupling beam structure includes two quarter-wavelength matched beams and an anchor located at a nodal point for coupling the two quarter-wavelength matched beams and ring resonator structures. The symmetric ring design also provides a differential drive and sense configuration while balancing the driving forces about the anchor located at the center of the beam structure. The system exhibits low energy losses while providing large sensing signals and a high quality factor (Q) of about 186,000 at a resonant frequency of about twenty-nine (29) MHz.
