Wearable sensors have been popularly used in many applications with the development of computer science and engineering. However, wearables for biomechanical feedback in motor learning and training are still rare. Therefore, this thesis focuses on developing an efficient and cost-effective wireless sensor system through a case study on the hammer throw. The results have shown that the proposed reconfigurable and wearable system can implement real-time biomechanical feedback in the hammer-throw training. Furthermore, the experimental results suggest that various throw-control patterns could be identified by using one tension-sensor and two inertial measurement units (i.e., more superior practicality than 3D motion capture), indicating that the low-cost wearable system has potential to substitute the expensive 3D motion capture technology. The proposed system can be easily modified and applied to many other applications, including but not limited to healthcare, rehabilitation, and smart homes, etc.
