(a) Locally developed electrically actuated testing rig is proficient for applying five types of strain for thin films. It works for stretching, compression, bending (upside, downwards), and torsion (clockwise, anti-clockwise). (b) The clamp structure contains jaws to hold the sensor in place and to apply strain. One of the jaws is fixed, while the other is electrically actuated.
