    Abstract: A photoacoustic gas sensor device for analyzing gas includes an emitter module and a pressure-sensitive module. The emitter module is arranged on a carrier substrate and emits light pulses. The pressure-sensitive module is arranged on the carrier substrate within a reference gas volume. The reference gas volume is separated from a volume intended to be filled with a gas to be analyzed. Further, the pressure-sensitive module generates a sensor signal indicating information on an acoustic wave caused by light pulses emitted by the emitter module interacting with a reference gas within the reference gas volume. Additionally, the emitter module is arranged so that light pulses emitted by the emitter module reach the reference gas volume after crossing the volume intended to be filled with the gas to be analyzed.

    Abstract: A sound transducer structure includes a membrane and a counter electrode. The membrane includes a first main surface in a sound transducing region made of a membrane material, and an edge region. The counter electrode includes a second main surface arranged in parallel to the first main surface of the membrane on a side of a free volume opposite the first main surface of the membrane. A plurality of elevations extend in the sound transducing region from the second main surface of the counter electrode into the free volume. The membrane and the counter electrode are arranged to provide a capacity therebetween. The membrane comprises a corrugation groove extending in the sound transducing region from the first main surface of the membrane into the free volume.

    Abstract: A photo-acoustic gas sensor includes a light emitter unit having a light emitter configured to emit a beam of light pulses with a predetermined repetition frequency and a wavelength corresponding to an absorption band of a gas to be sensed, and a detector unit having a microphone. The light emitter unit is arranged so that the beam of light pulses traverses an area configured to accommodate the gas. The detector unit is arranged so that the microphone can receive a signal oscillating with the repetition frequency.

    Abstract: A digital loudspeaker includes a substrate, a first stator fixed with respect to the substrate, a second stator fixed with respect to the substrate and spaced at a distance from the first stator, and a membrane between the first stator and the second stator. The membrane is displaceable between a first position in which the membrane mechanically contacts the first stator and a second position in which the membrane mechanically contacts the second stator. The first stator and the second stator are arranged to electrostatically move the membrane from a rest position spaced apart from the first position and the second position to the first position and the second position, respectively.
