Characteristics of a novel biaxial capacitive MEMS accelerometer
|
Abstract:
A novel MEMS accelerometer with grid strip capacitors is developed.The mechanical and electrical noise can be reduced greatly for the novel structure design.ANSOFT-Maxwell software was used to analyze the fringing electric field of the grid strip structure and its effects on the designed accelerometer.The effects of the width,thickness and overlapping width of the grid strip on the sensing capacitance are analyzed by using the ANSOFT-Maxwell software.The results show that the parameters have little effect o...
