A method for measuring the center position of the two dimensional distributed load is proposed and the basic experimental results for its verification are shown.The sensor used in this method is constructed of pressure-conductive rubber whose registance per unit area varies with the distributed load, a pair of conductive materials which contact with each surface of the rubber, two pair of metal electrodes which are positioned at each edge of the conductive materials and some electric circuits for the voltage operation of the electrodes.In this paper, it is shown that this sensor can concurrently detect two available values that are the center position of the two dimensional distributed load on the surface of the sensor by specifying the orthogonal cuvilinear coordinates and the total load of the distribution. This paper also shows that according to the characteristics of pressure-conductive rubber, these values have various meanings. Finally, this method is verified by the basic experiment.By this method, the value of each point of the distribution can not be measured, but this method has advantages that (1) as the distribution is not digitized, the sensor, can deal with the small range of the distribution, (2) the low cost sensor is realized and (3) the sensor can take any three dimensional surface.This sensor can be applicable to the measurement of the center of gravity on the sole of a foot, the codeless pen tablet for the computer input and the tactile sensor of robots.
