Abstract
The MEMS switch has a high-impedance state and a low-impedance state for biasing a capacitive sensor, and includes an actuation bias terminal, a sense bias terminal, a switch control terminal, a sense node terminal, and a spring. The actuation bias terminal and the sense bias terminal reside in a released region of the switch. The sense bias terminal is physically coupled to the actuation bias terminal by a dielectric which electrically isolates the sense bias terminal from the actuation bias terminal. The switch control terminal is separated from the sense bias terminal by a first air gap, and the sense node terminal is separated from the sense bias terminal by a second air gap. The spring supports the actuation bias terminal, the sense bias terminal, and the dielectric.
