  • Patent number: 4695963
    Abstract: A pressure sense recognition control system having at least one pressure sensor module for detecting the two-dimensional distribution of the component forces in the three directions in the rectangular coordinate system of a force applied to the pressure receiving surface of the pressure sensor modules. The pressure sensor module has at least one pressure sensor cell having a pressure sensing member made of single crystal silicon, and a plurality of diffusion type strain gauges provided on the surfaces of the pressure sensing member which are substantially perpendicular to the pressure receiving surface and for detecting the three component forces applied to the pressure surfaces in response to the changes of an output of a bridge composed of the strain gauges. These members are mounted on an object, the drive of which is to be controlled.
