ABSTRACT:
A pressure sensor has a housing having a first block and a second block provided therein. A force to be measured applies upon a upper face of the first block. An upper face of the second block makes contact with a base face of the first block. Piezoresistive elements are formed within the base face of the first block. The resistance values of these piezoresistive elements change as contacting pressure between the first block and the second block changes. A first electrode is formed on an upper face of the first block. A second electrode is formed on a base face of the second block. Electrical characteristics between the first electrode and the second electrode change following change in the contacting pressure between the first block and the second block.
