摘要:
A sensor component and a method for manufacturing a sensor component, in which a sealing passivation of a sensor layer may be dispensed with. For this purpose, the sensor component includes, in particular, a thin film high-pressure sensor, a deformation body and a piezoresistive sensor layer, which is applied to the deformation body, the piezoresistive sensor layer including at least one metal as well as carbon and/or hydrocarbon and terminating the layer structure of the sensor component. Based on the materials used a sealing cover of the sensor layer by a thin film passivation layer may be dispensed with. Additional contact layers for contacting the sensor layer may advantageously also be dispensed with. Contacting may then take place directly on the sensor layer, using a bond wire.
摘要:
Method for applying a coating layer to a tubular intraluminal implant, in particular to a vascular support (stent), where the surface of the implant is perforated by a plurality of apertures, and where the coating layer is produced by deposition of material onto the surface of the implant. The implant is first pushed onto a cylindrical holder 4, a sacrificial material, in particular copper, is then deposited onto the surface of the implant until the deposited sacrificial material almost entirely fills the apertures, the coating layer is then deposited onto the surface of the implant provided with sacrificial material, and then the cylindrical holder 4 and the sacrificial material situated in the apertures 3 are removed.
摘要:
A process for producing a self-supporting layer made of a titanium and nickel alloy with superelastic and/or shape memory properties has the following steps: a substrate entirely or at least mainly made of silicon is provided, a layer of said alloy is applied to a surface of the substrate, the substrate with the desired form is cut out of a wafer or formed by a wafer with the desired form; at least some zones of the lateral surfaces of the substrate adjoining the zones of the surface of the substrate which receive the layer are subjected to an etching process; a layer of said alloy is applied to the surface of the substrate; and the substrate is removed from the applied layer. Also disclosed is a substrate suitable for carrying out the process and an object, in particular an implant, comprising at least one layer produced by this process.
