A recently granted patent (Publication Number: US11889282B2) discloses a micro electro mechanical system (MEMS) device featuring a unique design. The device includes a substrate with a back cavity, a diaphragm covering the cavity composed of two membranes with an accommodating space between them, supports connecting the membranes, and a counter electrode. Ventilation slots are provided on the diaphragm, and the membranes have distinct regions - an electrode region and a semiconductor material region with conductive ions. The device also includes a bonding pad connected to an external circuit and conducting tracks avoiding the ventilation slots.

Furthermore, the MEMS device described in the patent includes additional features such as protrusions on the membranes connected by supports, through holes on the electrode region, and support members arranged concentrically with notches between sections. The design of the device allows for efficient operation and structural integrity, with the supports and membranes configured in a specific manner to enhance performance. These innovative features set this MEMS device apart from conventional designs, offering potential benefits in various applications where MEMS technology is utilized.
