In the fields of material science, MEMS development and quality control, accurate force sensing is an important objective. In other areas such as the testing of biomaterials, tissue engineering and mechanobiology small force measurements are applied also.
Capacitive MEMS force sensing instruments have become commercially available and are provided by the company FemtoTools and its distributors. FemtoTools is a Swiss high-tech company that offers award-winning, high-precision instruments for mechanical testing and robotic handling in the micro and milligram range. The system range comprises high-precision microforce sensing probes, force sensing microgrippers and micro manipulators as well as all necessary control units and software. The modular design allows the configuration of complete systems which perfectly fit the users’ applications. FemtoTools’ instruments have already been used world wide by scientists and application engineers who work in bio or material sciences.
Different sensor models are available with a force range going from 0.05 micrograms up to 1000 milligrams.
