Description

technical field [0001] The invention relates to a flexible shoulder joint motion sensor and a measuring method thereof, belonging to the technical field of sensors. The sensor can realize the static and dynamic angle detection of the lateral and lateral motion angles of the human shoulder joint, and is suitable for rehabilitation medicine, motion monitoring and other fields. Background technique [0002] Human shoulder joint motion sensing is to obtain the rotation angle signal during motion through the sensor that can monitor the shoulder joint motion, and realize the real-time detection of the shoulder joint motion angle. At present, there are many sensors that can be applied to shoulder joint motion, involving industries such as machining, aerospace, intelligent robots and other fields. Due to the diversity and limitation of angle measurement, it needs to be further improved and developed in the application field. [0003] At present, the angle sensors that can be appli...
