| Outline of Final Research Achievements |
Wearable sensor in the cloth material was designed for motion analysis. This specific motion analysis system could measure the joint flexion angle including elbow and wrist joint, and rotation angle of the forearm supination and pronation. In the experiment, strain gauge was fixed to the cloth material using an adhesive tape, at around the elbow joint and the wrist joint. Concerning the accuracy, mean of measuring error was 2.97% in flexion/extension of the elbow joint. Similarly, mean of measuring error in supination/pronation of the forearm was 4.2%. After all our wearable sensor showed a excellent accuracy enough to measure not only the daily living motion but the sports activity motion in the athletic fields.
