Simulation and experimental verification of flexible cellulose acetate haptic array actuator

摘要

This paper reports the experiment and finite element (FEM) simulation of an array type film haptic actuator. Haptic actuator was made of cellulose acetate films and adhesive tape separator between two films. For preparing 3×3 array haptic device, nine identical actuators were joined together. The purpose of an actuator is to create vibration feedback resulting from applied potential. Cellulose acetate based film actuator is suitable for transparent haptic devices because of its high dielectric constant, flexibility and transparency. The focus of this paper is to use a finite element model to simulate and analysis haptic actuator and verify that result with experiment. The reason of preferring ANSYS simulation is for the flexibility of modeling, time saving, post processing criteria and result accuracy.
