Title: Weiqi Li: Innovator in Acoustic Resonator Technology
Introduction
Weiqi Li is a notable inventor based in San Jose, California, recognized for his contributions to the field of acoustic resonators. With a total of three patents to his name, Li has made significant advancements in the design and functionality of acoustic devices.
Latest Patents
One of Li's latest patents involves an innovative acoustic resonator. This resonator features a piezoelectric stack that includes a piezoelectric layer with a top and bottom surface. It is equipped with a top electrode layer positioned above the top surface and a bottom electrode layer located beneath the bottom surface. Additionally, several acoustic wave reflectors are placed on the side of the bottom electrode layer that is opposite the piezoelectric layer. Each reflector consists of a high acoustic impedance layer and may also include a low acoustic impedance layer. The design incorporates a tether that extends laterally to the stacking direction of the piezoelectric layers. A supporting structure is coupled to the tether, which anchors the acoustic resonator. To prevent resonant waves from escaping during operation, a mirror, one or more phononic crystals, or both may be positioned near the tether opposite the acoustic resonator.
