This thesis covers the design, fabrication, and testing of low-power electrostatically actuated MEMS relays. These relays can be used to enable ultra-low power operation of a sensor node while waiting for a signal of interest, significantly increasing the battery life. Electrostatic MEMS relays are fabricated on silicon-on-insulator wafers using a one-mask process with tools available in the Cornell Nanofabrication Facility (CNF). Tests of the fabricated devices are then processed and automated using Python and Arduino technology to control various test equipment. The resulting MEMS relay is able to be actuated using an external sensor.
