Sensors, Vol. 17, Pages 2708: Wearable Stretch Sensors for Motion Measurement of the Wrist Joint Based on Dielectric Elastomers Sensors doi: 10.3390/s17122708 Authors: Bo Huang Mingyu Li Tao Mei David McCoul Shihao Qin Zhanfeng Zhao Jianwen Zhao Motion capture of the human body potentially holds great significance for exoskeleton robots, human-computer interaction, sports analysis, rehabilitation research, and many other areas. Dielectric elastomer sensors (DESs) are excellent candidates for wearable human motion capture systems because of their intrinsic characteristics of softness, light weight, and compliance. In this paper, DESs were applied to measure all component motions of the wrist joints. Five sensors were mounted to different positions on the wrist, and each one is for one component motion. To find the best position to mount the sensors, the distribution of the muscles is analyzed. Even so, the component motions and the deformation of the sensors are coupled; therefore, a decoupling method was developed. By the decoupling algorithm, all component motions can be measured with a precision of 5°, which meets the requirements of general motion capture systems.
