Abstract:
The aim of the current study was to reduce both the size as well as production costs of current designs whilst retaining the general architectural principles and find a solution lending itself to batch processing. The designs result in a new method for connecting the sensor to the outside being necessary. This can be achieved by thin film on a steel substrate or using ceramic technology such as LTCC. Special attention is paid to the flexible membranes. Small membranes with high corrugations made of nickel are separated in a standard galvanic process on the housing. The manufactured sensors are characterised.
