With the example of vibrating beam of difference boundary conditions,a new methodology is presented to design volume displacement sensor using shaped PVDF film on the basis of mode orthogonal property and integration in parts approach.Design of mode orthogonal can only used to measure one end of the vibrating plate volume displacement,but the integration in parts approach is feasible to measure each group of boundary condition.The PVDF sensor shape is shown not only independent of property of the excitation(the type,position and frequency,etc.),but also independent of material characteristics of vibrating plate.
