Theoretical and experimental analysis of a piezoelectric tactile sensor for use in endoscopic surgery

Abstract

This paper describes design, theoretical, and experimental analysis of a polyvinylidene fluoride (PVDF) tactile sensor, which could be integrated with an endoscopic grasper. The sensor exhibited high force sensitivity and linearity. Finite element analysis was employed to study the structural analysis of the tactile sensor with various load application and the results of this modelling are presented as the shear stress distribution and deformation contours. A comparison was made between the theoretical modeling and the experimental results.
