Abstract
The rapid development of the fifth generation technology poses more challenges in the human motion inspection field. In this study, a nanogenerator, made by PVDF, ionic hydrogel, and PDMS, is used. Furthermore, a transparent, stretchable, and biocompatible PENG (TSB-PENG) is presented, which can be used as a self-powered sensor attached to the athlete’s joints, which helps to monitor the training and improve the subject’s performance. This device shows the ability to maintain a relatively stable output, under various external environments (e.g., inorganic salt, organic matter and temperature). Additionally, TSB-PENG can supply power to small-scale electronic equipment, such as Bluetooth transmitting motion data in real time. This study can provide a new approach to designing lossless, real-time, portable, and durable self-powered sensors in the sports motoring field.
Highlights
The world is entering the era of Internet of Things (IoT) at an accelerated speed, based on the rapid development of the fifth generation technology [1,2,3,4]
The average light transmittances of the PDMS, PVDF, and PAAM-lithium chloride (LiCl) hydrogels were above 86%
TSB-PEGN can keep a stable energy of the human body into electrical energy, charge capacitor, Bluetooth etc
Summary
The world is entering the era of Internet of Things (IoT) at an accelerated speed, based on the rapid development of the fifth generation technology [1,2,3,4]. According to known research achievements, wearable electronic equipment has already been applied to the theory and practice of sports training, such as basketball, athletics and swimming [14,15,16,17,18,19,20]. In basketball, the winning factors are mainly the transformation of attack and defense [21,22]. It is manifested as the center player’s pivot teamwork, perfect passing, and dribbling skills, as well as the cooperation level of the whole team, where the center player’s passing method is important to the game [23,24,25]. Audio/video and virtual reality equipment are used to monitor the training process of the center player [26,27,28,29]
