Physics and microsystems technology Looking back and ´conecting the dots´, we can state that the high-tech research fields such as laser physics and the highly integrated microsystems technology (MEMS), combined with the scientific mindset of the physicist, ensure successful work in the Deep Tech segment to develop sophisticated innovative solutions together with our clients. …
GitHub repositories We make our program codes and numerical simulation models (FEM, CFD) that we have developed over time available to the public in the sense of open source collaboration. We have also compiled the experimental measurements of our relevant scientific work as Open Data. | Open Source | Open Data | Open Access…
Piezoelectric Silicon Sensors & Actuators HighTech experience that counts This project list contains a selection of projects that demonstrate our profound, long-term experience in product development and management of more complex technology projects in high-tech industries, namely in the areas of: Sensors & Actuators, MEMS & Semiconductor Manufacturing, including the semiconductor industry, as…
Project management models Individual project work at our clients usually requires a process model with client-specific adaptations. These cannot usually be adequately covered by standardized processes. We have designed various industry-specific PM models and successfully operationalized them in practice with different clients: Industry-specific PM models Development of specific PM process models for the…

Monolithic bridge-on-diaphragm microstructures Abstract Monolithic bridge-on-diaphragm (BOD) microstructures for sensor applications were fabricated by means of laser machining and anisotropic etching techniques. The pressure-frequency-characteristic was measured by acoustical excitation of the microbridge to resonant vibrations and optical detection of the resonance frequency. In the pressure range between 0.8 bar and +1.0 bar the pressure-frequency-characteristic is…
