parallel tensile testing of silicon with integrated strain gauge

uesugi_enIn order to shorten a testing time for evaluation of tensile-mode fatigue properties of single crystal silicon, we have developed parallelized tensile-testing method with an integrated strain gauge. The testing method increases a loading frequency to higher than 100 Hz because of a high stiffness of testing system, and shortens a testing time per one specimen due to the parallelization. The integrated strain gauge is based on a piezoresistive effect of single crystal silicon. Low-noise output is acquired from an integrated bridge circuit on a testing chip.
