Finite element modeling of frequency-analog sensors HSG-IMIT Institute for Micro- and Information Technology of the Hahn-Schickard-Gesellschaft for Applied Research e.V., Villingen-Schwenningen 2.1 Introduction 2.1.1 Functional principle of resonant sensors The principle of a resonant sensor is based on the dependence of the natural frequency of the resonator on an external physical variable…
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), which 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…
