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