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 external forces, causing a corresponding change in resistance value. The strain gauge is attached to the object being measured, allowing it to experience the same strain. When bent, the metal foil inside the gauge deforms accordingly. Many metals exhibit changes in resistance during mechanical bending.
