1. A contact-pressure detecting apparatus, comprising:

  • a base having an arbitrary shape with a hollow space therein;

    at least one area on a surface of the base having a polygonal periphery;

    pressure sensors located at three or more vertices of each polygonal shaped area; and

    a respective plate corresponding with each such polygonal shaped area of the surface of the base, each plate covering its respective polygonal shaped area of the surface of the base, each plate sandwiching the at least three pressure sensors between the plate and the base;

    a calculating section positioned within the hollow space, the calculating section deriving pressure measurement information and position of pressure application information from the pressure sensors.
