This paper presents the modal analysis of cantilever plate with and without piezoelectric patch by using Finite Element Analysis (Ansys) software. A modal analysis was carried out on cantilever plate having piezoelectric patch at 6 different locations. By comparison we observed that natural frequency of plate was increased with first 2 locations of PZT patch and natural frequency was decreased with next 4 locations of PZT patch. PZT patch is used due to it Direct Piezoelectric Effect with which we can sense the physical deformation of the plate, in turn this plate can be used in sensing of deformations of different objects with which it is attached to.
