Abstract: Acoustic and other activity detection signaling is provided herein. Operations of a method can include determining a micro-electromechanical system (MEMS) device is no longer in an initialization state and receiving a first signal that instructs the MEMS device to perform event activity detection. The method can also include receiving one or more event signals and determining that an event signal of one or more event signals satisfies a defined event characteristic. The method can also include outputting a second signal that comprises information indicative of a detection of event activity at the MEMS device being more than the defined event characteristic.

Abstract: A device includes a micro-electromechanical system (MEMS) element configured to sense acoustic signals. The device also includes a circuitry configured to enable the microphone element to sense the acoustic signals. The circuitry is further configured to disable the microphone element to prevent the microphone element to sense the acoustic signals. It is appreciated that the circuitry is further configured to apply a test signal to the MEMS element when the microphone element is disabled. The microphone element outputs a signal in response to the test signal to the circuitry. The circuitry in response to the output signal with a first value determines that a diaphragm of the MEMS element is nonoperational and the circuitry in response to the output signal with a second value determines that the diaphragm of the MEMS element is operational.
