Embodiment Construction

[0040] Referring to the accompanying drawings, the present invention will be further described in detail with specific embodiments. Take the detection of the amount of movement of the shoulder joint as an example for illustration.

[0041]The shoulder joint is composed of six joints: the scapulohumeral joint, the glenohumeral joint, the acromioclavicular joint, the sternoclavicular joint, the coracoclavicular joint, and the scapulothoracic joint. Because the humeral head is large and spherical, the glenoid is shallow and small, and only covers 1 / 3 of the humeral head, and the joint capsule is thin and loose, so the shoulder joint is the joint with the largest and most flexible range of motion in the human body. It can be used as an anterior joint. Flexion, extension, abduction, horizontal adduction, horizontal extension, internal rotation and external rotation. The following will measure the various sub-motions of the shoulder joint, and on this basis, give a decoupling metho...

Abstract

The invention relates to a human body motion detection method based on a dielectric elastomer sensor, which solves the technical problems of low precision and low reliability in the prior art when using a dielectric elastomer sensor for human body motion detection, and will be used for The first dielectric elastomer sensor for measuring the forward flexion of the shoulder joint is pasted vertically on the skin at the external oblique muscle just below the armpit of the human body, and the lower end of the first dielectric elastomer sensor is aligned with the second rib; it will be used for The second dielectric elastomer sensor for measuring the extension of the shoulder joint was pasted on the front of the shoulder joint and arranged along the texture of the front of the deltoid muscle; the third dielectric elastomer sensor for measuring the abduction of the shoulder joint was placed vertically Stick it directly on the skin on the outside of the pectoralis major muscle, align one end of the third dielectric elastomer sensor with the lower edge of the pectoralis major muscle; place the fourth dielectric elastomer sensor for measuring the horizontal adduction movement of the shoulder joint along the deltoid muscle The texture on the back side is pasted; the invention is widely used in the technical field of human motion detection.

Description

technical field [0001] The present invention relates to the technical field of human motion detection, in particular to a human motion detection method based on a dielectric elastomer sensor. Background technique [0002] In recent years, the demand for human motion capture has become more and more in the fields of sports and fitness, human-computer interaction, medical rehabilitation, entertainment and military. For example, in the field of entertainment, data gloves are used to capture human hand movements and transmit relevant data to the virtual environment in real time, making the interaction between players and the virtual world more direct and natural, greatly enhancing the game experience. [0003] At present, soft sensors are widely used in human motion detection devices, and common soft sensors include conductive rubber, conductive fiber / fabric, polyvinylidene fluoride (Polyvinylidene Fluoride, PVDF) and the like. Among these types of soft sensors, conductive rubb...
