Research progress on residual stress in micromechanical pressure sensor is reviewed. Research progress and existing deficiencies of micromechanical pressure sensor at home and abroad are summarized. The influences of residual stress on sensors in aspect of zero offset
zero temperature coefficient
output nonlinear and output frequency are analyzed. Influence of material properties
processing temperature on residual stress is summarized.Development and trend of residual stress measurement are prospected. It is pointed out that residual stress can be controlled or utilized through optimizing structure design in order to improve stability.
