Patent number: 12028679Abstract: Provided is an electrostatic clutch. The electrostatic clutch includes: multiple arrays of HIN electrodes, a respective pass-through channel being formed between any two arrays of the multiple arrays of HIN electrodes; and multiple arrays of biased electrodes, each array of the multiple arrays of biased electrodes moving back and forth in the respective pass-through channel such that electrostatic force is generated between the multiple arrays of biased electrodes and the multiple arrays of HIN electrodes. Such configuration allows microphone performance over a wide range of atmospheric pressures which is likely expected by applications. This is achieved electrostatically in a purely passive way having advantages over other designs which require complex electronics and active control.
