Pressure-conductive rubber has many excellent features such as high Flexibility, workability and ease in the fabrication of thin films. However this material shows hysteresis between pressure and resistance values. To date, this property has not been investigated in detail. In this paper, evaluation of pressure sensing characteristics of pressure-conductive rubber, including hysteresis, time response and creep effect, was carried out. A pressure loading instrument in which motion could be precisely controlled was constructed to test its characteristics experimentally. The hysteresis effect, that is caused by the stress-strain characteristics of the material, was experimentally clarified. An index for showing the degree of this hysteresis was proposed. As for the time response, a time lag of 0. 2 [ms] was observed. As for the creep effect, resistance of the rubber remained constant for a long time under constant loading.
