Abstract
There are many inventions described and illustrated herein, as well as many aspects and embodiments of those inventions. In one aspect, the present invention is directed to one or more microelectromechanical ring resonator structures having a circular or substantially circular outer surface and a circular or substantially circular inner surface. The microelectromechanical ring resonator(s) include an anchor support element having an impedance matching structure coupled to at least one substrate anchor. The impedance matching structure may be a beam, having a predetermined length, which couples the ring resonator(s) to substrate anchor. In one embodiment, the impedance matching structure operates in a bulk-elongation mode. In another embodiment, the impedance matching structure operates in a flexure mode. In operation, when induced, the microelectromechanical ring resonator structure oscillates in an elongating/compressing or breathing mode (or in a primarily or substantially elongating or breathing mode). In this regard, the ring resonator structure exhibits an elongating/compressing-like or breathing-like motion.
