A Box-Shaped Triboelectric Nanogenerator for Basketball Training Monitoring

The posture monitoring of basketball is very important for daily training and skill improvement, and the research and development of related sensor technology is extremely urgent. Here, we design a box-shaped triboelectric nanogenerator (BS-TENG) to harvest mechanical energy and serve as the smart sport sensor. The BS-TENG can realize two working modes, leading to harvest both active and passive mechanical energy. This unique box structure enables to be integrated on the floor, which can play the role of smart sport floor. Furthermore, under different basketball posture (such as walk with the ball, dribble and shoot), the BS-TENG can generate different voltage signal, which make BS-TENG can serve as the self-powered sport sensor. We think this design will promote the development of intelligent sports devices.
