Multiplexed Robotic Tactile Sensor Fabricated from Polyvinylidene Fluoride Film

Abstract

This research effort involved the design, fabrication and evaluation of a multiplexed robotic tactile sensor fabricated from polyvinylidene fluoride (PVDF) film. A 16x16 electrode array was designed, each electrode encompassing a 250 microns x 250 microns square area, separated by a distance of 150 microns. A resident analog multiplexer was designed to assist in the acquisition of electrical signals from the array. Inherent within the multiplexer were analog transmission gates which provided a bidirectional flow of charge to each electrode. This provided a means of initializing the bias state of the PVDF film prior to the application of a load. (JES)
