The evaluation of mechanical properties including static and fatigue behavior is essential issue for developing a reliable micro-sized machine in service operation. But there has been an absence of the standard test procedure for micro-sized materials. Therefore, the evaluation of mechanical properties including reliability and durability has not been performed. In the present study, we have designed and manufactured the fatigue tester for micro-sized materials. Fatigue tests have been performed for aluminum fine wire with 25μm diameter and the S-N diagram has been obtained. It was investigated that the number of cycles to failure showed wide distribution on each cyclic stress revel.
