| Abstract: | The finite element method is used to calculate the equi-rigidity of piezoresistive sensor's elastic membrane,and the calculational method is given.Only when the rigidity of the elastic membranes of outside annulus is equal to that of inside annulus,the bearing force surface can be ensured to make translational motion,and the defects caused by unequi-rigidity of elastic membrane can be overcome.Therefore,the sensor's precision can be improved and its life can be proloned. |
