Abstract

We are developing a wireless system that measures online the forces between foot and insole with a low-cost laminated capacitive sensor matrix. This measurement system can be utilized to monitor the timing and movements of the legs of an athlete during throwing, jumping and running in various sports events. The measured data is intended to be used to improve coaching. We chose the javelin throw event as a case study for our sensor system. We measured the force signals under both feet during several throws. Analysis showed that the measured signals provide additional information for coaching.
