The working principle of resistance strain gauge is based on the strain effect produced by mechanical deformation, namely the role of conductor or semiconductor materials in the external force when the resistance value changes, this phenomenon is called "strain effect".

The strain gauge is attached to the object to be measured, so that it is bent along with the strain of the measured object. A lot of metal in the mechanical bending of its resistance will change.
