Numerical analysis of pull-in voltage in contact MEMS switch with double actuated electrodes

This paper presents the numerical analysis of pull-in voltage for a contact MEMS switch with a couple of electrodes. The lumped-model for double actuated coupled parallel-plate actuators is applied to describe the pull-in phenomenon. And based on the pull-in analysis results, some optimizing approaches are developed to lower the pull-in voltage for a contact MEMS switch.
