    摘要： The present invention relates to a micro-electromechanical transducer comprising a pressure detecting arrangement adapted to detect generated pressure variations, and provide an output signal in response to the detected pressure variations, wherein the pressure detecting arrangement comprises a microphone cartridge and a signal processing unit; a pressure generating arrangement adapted to generate pressure variations in response to vibrations thereof; and a volume separating element comprising one or more openings, wherein the microphone cartridge is at least partly arranged in a first opening of the volume separating element in order to reduce the overall height of the micro-electromechanical transducer. The present invention further relates to a hearing device comprising a micro-electromechanical transducer.

    摘要： A magnetic tunnel junction (MTJ) based sensor device includes a MTJ element and processing circuitry. The MTJ element includes a free layer, a pinned layer, an elastic layer, and a tunnel barrier. The free layer is spaced apart from the pinned layer by the tunnel barrier and the elastic layer. The processing circuitry is configured to measure a resistance at the MTJ element and determine whether mechanical shock and vibration has occurred based on the resistance at the MTJ element.
