For the development of high-quality sports equipment, the increase in performance is the utmost requirement. However, it is not always trivial to find a direct correlation between the construction of sports equipment and the immediate power values of an athlete.Miniaturized MEMS sensors can provide here the necessary information for the tar-geted development of high quality sports equipment as functional apparel and shoes. Together with the adidas – FUTURE TEAM, we develop MEMS sensors for different applications. Typical examples are e.g. the fast multi- channel data logger for motion sensors with up to 6 IMUs @ 1 kHz sample rate or the wireless climate sensor net-work for humidity measurements within apparel and shoes.
