Abstract
A dynamic capacitive sensor configuration is disclosed which imposes minimal force and resistance to motion on the moving electrode. Moving electrodes avoid adverse effects of large bias voltages such as pull-in instability, despite arbitrary levels of compliance. This configuration facilitates incorporation of highly compliant and thin electrode materials that present the least possible resistance to motion. This type of material is particularly useful for sensing sound. A large bias voltage can be applied without influencing its motion, e.g., 400 V. The electrical sensitivity to sound is high, e.g., approximately 0.5 volts/pascal, two orders of magnitude greater than typical acoustic sensors.
