    摘要: A micromechanical pressure sensor which is made up of at least one first component element and a second component element bordering on the first component element. In this context, the first component element includes at least one diaphragm and one cavity. The cavity is arranged or structured so that the medium to be measured gains access to the diaphragm through the cavity. In addition, in the second component element an opening is provided which guides the medium to be measured to the cavity. At least a part of the cavity represents an extension, without a transition, of the opening in the second component.

    摘要: A micromechanical sensor element (1) is provided, which has a sealed diaphragm (2) affixed in a frame (3), exhibits high sensitivity at high overload resistance and has a small size, and which allows a piezoresistive measured-value acquisition. To this end, at least one carrier element (4), which is connected to the frame (3) via at least one connection link (5), is formed in the region of the diaphragm (2). Furthermore, piezoresistors (6) for detecting a deformation are situated in the region of the connection link (5).
