A Self-Powered Intelligent Tactile Electric Skin Based on ZnO/Fabrics for Real-Time Monitoring Grabbing of Snowboard

摘要

Real-time monitoring of the position and duration of the snowboarder's grab in the air plays an very important role in scientifically improving the stability and innovation of the movement. Meanwhile, it also provides accurate scientific basis and judgment for the judges to identify the movement in the competition. By using four-needle ZnO nanowires combined with ordinary textile fabrics, a flexible device that can be attached to skis has been created. The device could output piezoelectric signals (working without external power source) served as both power source and sensing signal. Based on this, a snowboard has been modified to monitor the contact position and duration, when any touch or grab occurs on the snowboard. Undeniably, this work has created a new and more scientific monitoring system for snowboarding competitions and training. In addition, it's provide a viable method to promote the directions of sport competitions and equipment with constantly updating portable equipment.
