摘要： A force sensing element is provided with a gauge portion and a plurality of electrodes. The gauge portion is formed of an n-type semiconductor substrate whose (100)-face serves as a main face, a p-type semiconductor substrate whose (110)-face serves as a main face, or a p-type semiconductor substrate whose (111)-face serves as a main face, and is pressed in a thickness direction of the semiconductor substrate upon receiving a force. The electrodes are electrically connected to the gauge portion such that a current path extending in a direction corresponding to the thickness direction of the semiconductor substrate is formed in the gauge portion. The force sensing element thus constructed makes it possible to detect a force with high precision.

摘要： 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.
