Flexible fabric sensor for measuring human body knee joint movement and method thereof

Abstract

The invention belongs to the field of wearable sensors, and particularly discloses a novel flexible fabric sensor for measuring human body knee joint movement and a method thereof. The current bending angle, formed when a user walks and does movement training, of the knee joint can be measured and output in real time. Common cloth is combined with conductive yarn, a sensitive unit of the flexible fabric sensor is developed, after the sensor is calibrated through a designed method, bending movement of the knee joint is converted into stretching movement of the flexible fabric sensor through a certain wearing mode, the problem that a rotating shaft moves when the knee joint rotates is effectively solved, and the current bending angle of the knee joint of the user is calculated and output. The flexible fabric sensor is convenient to use, low in cost and capable of being not limited by a field and measuring the bending angle of the knee joint of the user in a comfortable mode in real time and has high reliability and a good popularization prospect.

Description

technical field [0001] The invention belongs to the field of wearable sensors, and in particular relates to a novel flexible fabric sensor for measuring human knee joint motion and a method thereof. Background technique [0002] The monitoring of human posture and limb movement plays a vital role in medical rehabilitation, sports training and other fields. In the field of medical rehabilitation, accurate perception of body posture, visual presentation and remote monitoring allow patients to better understand their current physical recovery, while also enabling guardians and medical staff to have a more comprehensive understanding of the patient's condition. [0003] Studies have shown that stroke patients are more likely to be severely disabled than those with other medical conditions. After stroke patients are discharged from the hospital, rehabilitation exercise should start immediately, and the duration ranges from a few days to a year, so as to maximize the recovery of ...
