When the strain gauge is used, the strain gauge is attached to a measured object, so that the strain gauge stretches along with the deformation of the measured object, and the metal foil in the strain gauge stretches along with the deformation of the measured object. Since the resistance of the metal foil changes when the metal foil mechanically expands and contracts, the corresponding deformation can be measured by measuring the change of the resistance.
