With the rapid development of science and technology,it has become an important development direction of scientific research to assist movement through intelligent sensing devices. In order to collect the training data of table tennis players more conveniently and train them pertinently,a self driven information acquisition device based on single electrode triboelectric nanogenerator( TENG) is pro-posed. The device is composed of a table tennis racket and an electrode layer of a surface friction layer. Polydimethylsiloxane( PDMS) is selected as the friction layer material and carbon oil is used as the electrode layer material. At the same time,an array structure is de-signed that covers the entire table tennis racket surface. By collecting the electrical signals generated by the impact of the table tennis ball and the racket,the information such as the impact point and ball is obtained speed of the table tennis ball,which can be displayed in real time on the LabVIEW host computer. After testing,its output voltage can reach 11.2 V at the speed of 15 m/s of the ping-pong ball,and it can charge the 100 nF capacitor to 12 V within 60 s,which can be used as the power supply for micro electronic equipment, LED lights and timers.
