    摘要: Transducers comprising a frame structure made of piezoelectric material convert energy, through piezoelectric effect, between electrostatic energy associated with voltage differential between the electrodes sandwiching the frame structure and mechanical energy associated with deformation of the frame structure. Inertial sensors such as gyroscopes and accelerators, including inertial sensors comprising ring resonators, utilize said transducers both to generate oscillations of their resonators and to sense the changes in such oscillations produced, in the sensors' frame of reference, by Coriolis forces appearing due to the movement of the sensors.

    摘要: A method of producing a MEMS device provides a MEMS apparatus having released structure. The MEMS apparatus is formed at least in part from an SOI wafer having a first layer, a second layer spaced from the first layer, and an insulator layer between the first layer and second layer. The first layer has a top surface, while the second layer has a bottom surface facing the top surface. After providing the MEMS apparatus, the method increases the roughness of at least the top surface of the first layer or the bottom surface of the second layer.
