Abstract

The invention relates to a muscle activity observation device and a muscle activity observation method. This muscle activity observation device (10) is provided with a sensor module (20) and a detection module (30). The sensor module (20) is provided with a piezoelectric sensor (21). Output from the piezoelectric sensor (21) varies in accordance with the vibration of a tendon or muscle, and also in accordance with the extension and contraction of a tendon or muscle. A detection unit (31) of the detection module (30) detects the activity state of a tendon or muscle using a tremor signal and an extension / contraction signal outputted from the piezoelectric sensor (21).

Description

technical field [0001] The present invention relates to a muscle activity observation technique for observing muscle activity. Background technique [0002] The muscle movement detection device described in Patent Document 1 includes a sensor and a controller. The resistance of the sensor changes according to the contraction accompanying the movement of the muscle. The controller detects the voltage corresponding to muscle movement through the resistance of the sensor. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2010-29633 [0004] However, in the muscle motion detection device described in Patent Document 1, it is not possible to distinguish and measure isotonic contraction and isometric contraction. Therefore, it is difficult to accurately grasp the activity of the muscles. Contents of the invention [0005] Therefore, an object of the present invention is to provide a muscle activity observation technique capable of distinguishing between isotonic cont...
