International Solid-State Sensors, Actuators and Microsystems Conference
作者: Dorsey, K.L. Fedder, G.K. Department of Electrical and Computer Engineering Carnegie Mellon University Pittsburgh PA United States Robotics Institute Carnegie Mellon University Pittsburgh PA United States Institute for Complex and Engineered Systems Carnegie Mellon University Pittsburgh PA United States
Electrostatic actuation is commonly used for MEMS devices such as resonators, sensors, and RF switches, but parasitic charge in the dielectric layers of the devices may cause performance issues (e.g., drift, pull-in) ... 详细信息
