1A1-D01 Effect of the Electrode Pattern on Sensitivity of the Flexible Contact Sensor for Three Axis Load Measurement

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 loaded. Therefore, voltage changes between upper and lower electrodes can be measured. The other components are a skin layer and elastic sphere. The diameter of elastic sphere is 10mm. 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
