2A2-O15 Study and Research Aimed at Smaller Electrode Pattern of the Flexible Contact Sensor for Three Axis Load Measurement(Tactile and Force Sensing (1))

Abstract

In this paper, a flexible contact sensor for three axis load measurement was developed. The sensor is consists of three components. One is a load measurement layer which composed of upper electrode, PC/20wt.%VGCF and lower electrode. The conductive materials (PC/20wt.%VGCF) to use for the load measurement layer have the property that resistance values decrease when load is burdened. Therefore, voltage changes between upper and lower electrodes can be measured. The other components are a skin layer and elastic body. The pattern of upper electrode was changed, the effect of the electrode pattern on sensitivity of sensor for normal load and shearing load was investigated.
