Abstract
The application discloses a motion sensing jacket and a motion sensing system, wherein the motion sensing jacket comprises a jacket body and a distributed strain sensor; the jacket body is elastic; the distributed strain sensor comprises a stretchable conductor unit; the stretchable conductor unit comprises a plurality of concentrated sensing areas; the plurality of concentrated sensing areas are arranged on at least all or part of the following areas on the jacket body: an area corresponding to the latissimus dorsi muscle, an area corresponding to the trapezius muscle and an area corresponding to the biceps brachii muscle; and the concentrated sensing area is flexible so that the concentrated sensing area can generate an electrical property change following deformation of the jacket body. In the scheme, the concentrated sensing area is arranged on the area corresponding to the main active muscle on the jacket body, the activity of the corresponding part can be detected through the concentrated sensing area, and compared with optical positioning and motion capture technology and inertial motion capture technology, the concentrated sensing area has the characteristics of high precision, low cost and being not easily disturbed by the outside world.
