Abstract :
The mechanical fatigue behavior of MEMS gold structures is analyzed. Preliminary numerical FEM simulations are performed to determine the tension level in the material for a certain actuation voltage. Experimental tests are performed in order to monitor the damage accumulation during loading cycles; fatigue effect on material is evaluated through the monitoring of the pull-in voltage of the device.
