Description The working principle of a resistance strain gauge is based on the strain effect produced when a conductor or semiconductor material undergoes mechanical deformation under external forces, causing a corresponding change in resistance value. The strain gauge is attached to the object being measured so that the strain is transferred to the gauge, resulting in bending of the internal metal foil. Many metals exhibit a change in resistance during mechanical bending.
