In order to shorten testing time on tensile-mode fatigue testing of single crystal silicon micro structure, we have developed parallel tensile testing device with integrated strain gauge. This research proposes the parallel tensile fatigue test device integrating shear strain gauge as a load sensor and we aim to realize tensile fatigue test at high load frequency. The high stiffness helps decreasing actuator amplitude and increasing drive frequency, so fatigue testing time will shorten.
