Design and simulation of a piezoelectric sensor with applications in image stabilization

摘要

The piezoelectric materials used in the device industry with a very high market share are piezoceramics. They are used in medicine, robotics, mechanics but not least and the image stabilization. This material is easy to handle and with good properties related to mechanical and electric response. In full development are micro-electro-mechanical systems (MEMS) that bring with them new features, but also as small size, so they can be integrated into almost any device on the market. In this paper a piezoelectric accelerometer has been designed and optimized by simulation studies regarding the material and geometry. Based on electric response as function of mechanical deformation, an optimized geometry has been proposed and investigated by numerical analysis using Comsol Multiphysics software package. The simulation results for this new configuration are discussed and compared to basic accelerometers design.
