A Self-Powered Flexible Sensor for Speed Skating Land Technology Monitoring

Abstract

The Beijing Winter Olympics put forward the concept of scientific and technological Winter Olympics. Digital driving and precision training have become the main melody and high-frequency words in the field of sports training. In this context, the monitoring of athletes’ sports technology is particularly important. Here, a selfpowered flexible sensor based on T-ZnO/PVDF, PAAM-LiCl hydrogel electrode and FEP is proposed to monitor athletes’ sports technology. Based on the piezoelectric effect, the outputting piezoelectric signal by the selfpowered flexible sensor is not only the power supply energy of micro electronic device, but also the biosensor signal. In addition, the hydrogel electrode has the functions of anti-metal fatigue and stretchable flexibility, which can improve the adaptability of human motion machinery. The hybrid of polarized PVDF and T-ZnO enhances the overall outputting piezoelectric performance of the sensor. This study provides a new application idea for human mechanical energy storage, motion technology monitoring and the application of flexible portable self-powered sensors.
