Human Movement and Attitude Detection System Based on Flexible High Tensile Sensor of Single-Walled Carbon Nanotubes

Abstract

Excellent mechanical properties and outstanding optical and electrical properties of carbon nanotubes influence the fabrication of suitable devices and micro-electronic parts and systems, and they have been broadly applied in related fields. This paper aims to study the application of flexible high-stretch sensors of single-walled carbon nanotubes in human motion and attitude detection systems. In this paper, algorithm for human motion detection is proposed according to the content of human motion posture detection, and the properties of single-walled carbon tubing are analyzed in detail. The experimental results show that with the increase of carbon nanotube tubing, the reaction speed and sensitivity increase gradually. The reaction speed and sensitivity were 39% when the content was 1.5 wt%, 42% when the content was 2.0 wt%, and 59% when the content was 2.5 wt%. In summary, it can be found that within a certain range, the increase of carbon nanotube content can effectively reduce the hysteresis error of the sensor. It makes the sensitivity of the flexible high-stretch sensor higher, thereby improving the accuracy of the human motion attitude detection system.
