Title: The Innovative Contributions of David H Bernstein
Introduction
David H Bernstein is a notable inventor based in Oakland, CA. He has made significant contributions to the field of microelectromechanical systems (MEMS) with a total of 11 patents to his name. His work focuses on enhancing the performance and functionality of MEMS devices, which are crucial in various technological applications.
Latest Patents
Among his latest patents, Bernstein has developed a method for temperature compensation in MEMS resonators with isolated regions of distinct material. This innovation involves methods of forming MEMS resonators that contain a first structural material and a second structural material, allowing for tailored temperature coefficients of frequency (TCF). The first structural material has a different Young's modulus temperature coefficient than the second structural material. In one embodiment, the first structural material is formed on a substrate and patterned, while the second structural material is formed over the first and planarized to expose it. This results in a resonator that effectively utilizes both materials.
Another significant patent is for an out-of-plane resonator. This microelectromechanical system (MEMS) device features a resonator anchored to a substrate. The resonator includes a first strain gradient that statically deflects a released portion of the resonator in an out-of-plane direction. Additionally, the resonator incorporates a first electrode anchored to the substrate, which is designed to electrostatically drive the resonator in a mode that varies the displacement between the resonator and the first electrode. This innovative design enhances the performance of MEMS devices.
