The purpose of this thesis was to investigate the use of a microcontroller and mobile phone to create a highly mobile data acquisition device for human movement. Another aim was to make the technology as transparent as possible and explore development possibilities.Based on the description of use case scenarios the first set of system requirements were extracted. These system requirements lead to a set of technology requirements. A technology evaluation was conducted in order to find technology components for a prototype where the intended application were an internet connected center of pressure measurement application for an athlete in the ski jumping hill.The results include a working prototype that demonstrated the functionality. The technology has a lot of potential and room for improvements in order to be as technology transparent to the athletes as possible. The results of tests showed that there was a need for further analysis in regards to the performance of the prototype and what requirements that are needed when applied in the ski jumping hill.
