    摘要： A bending transducer device for generating electrical energy includes at least one elastically deformable support structure, one piezoelectric element, and a bearing device. The piezoelectric element is configured and situated on the support structure in such a way that the piezoelectric element is deformable due to a deformation of the support structure caused by vibration, and the support structure is supported vibration-capably in at least one bearing of the bearing device, the bearing being configured as an articulated receptacle, e.g., a hinge.

    摘要： A concept is proposed for a MEMS microphone which may be operated at a relatively low voltage level and still have comparatively high sensitivity. The component according to the present invention includes a micromechanical microphone structure having an acoustically active diaphragm which functions as a deflectable electrode of a microphone capacitor (1), and a stationary acoustically permeable counterelement which functions as a counter electrode of the microphone capacitor (1). The component also includes means for applying a high-frequency clock signal (2) to the microphone capacitor (1) and for applying the inverted clock signal (2′) to an adjustable but acoustically inactive compensation capacitor (7), an integrating operational amplifier (3) which integrates the sum of the current flow through the microphone capacitor (1) and the current flow through the compensation capacitor (7), a demodulator (4) for the output signal of the integrating operational amplifier (3), the demodulator being synchronized with the clock signal (2), and a low-pass filter for obtaining a microphone signal which corresponds to the changes in capacitance of the microphone capacitor (1), based on the output signal of the demodulator (4).

    摘要： A layer system and a method for producing the layer system are provided, the layer system having a silicon layer, on which at least regionally a passivating layer is superficially deposited, the passivating layer having a first, at least largely inorganic partial layer and a second, at least largely polymer partial layer. The method includes producing on the silicon layer, a first, inorganic partial layer, and producing on this first partial layer a second, polymer partial layer, which form the passivating layer. The production of the intermediate layer occurs in such a way that the intermediate layer in its surface area adjoining the first partial layer is composed as the first partial layer, and the intermediate layer in its surface area adjoining the second partial layer is composed as the second partial layer. The composition of the intermediate layer transitions, either continuously or in steps, from the composition corresponding to the first partial layer into the composition corresponding to the second partial layer.
