Abstract: A differential pressure sensor comprises a measuring diaphragm made of an electrically conductive material, two electrically insulating mating bodies, and at least one capacitive transducer. The measuring diaphragm is connected to the mating bodies in a pressure-tight manner with the formation of a measuring chamber in each case along a circumferential edge. The mating bodies each have a diaphragm bed which is concave in the center, wherein the mating bodies each have a pressure channel which extends through the mating body into the measuring chamber. The capacitive transducer has at least one mating body electrode which is formed by a metallic coating of the surface of the mating body in the region of the diaphragm bed and with which contact can be made by a metallic coating of the wall of the pressure channel.

Abstract: The invention permits the particularly simple, rapid and economic application of measuring elements (100) to objects to be measured (200). This is ensured by means of the integration of a functional material (140) on the connecting surface (113) of a measuring element (100). The mechanical connection is produced by activating the functional material (140). In this way, for example, the application times for strain sensors are drastically reduced. Furthermore, a defined thickness of the remaining functional material (140) is implemented and therefore reproducible properties of the connection are ensured.

Abstract: The invention makes it possible to determine a force vector that is applied to a tip of a minimally invasive surgical instrument. The force acts upon the housing, is directed to the base, and causes a deformation there in special beam structures. Said deformation is detected by tension-sensitive/extension-sensitive resistors whose changes are a measure for the applied force vector. The inventive measuring element comprises special mounting elements so as to be integrated into tube-type instruments such as guiding wires, fastening zones for additional components, an overload protection, and a head shape that is adapted to the treatment process.
