Multiple Functions Printed Circuit Triboelectric Nanogenerators-Based Metauniverse Sport Interactive System

Abstract

Metauniverse is a future society based on the convergence of the physical and the digital world, which is fully indebted to the sophisticated human-machine interface (HMI) to connect the two worlds. In this study, a metauniverse sport interactive system based on TENG has been developed, realizing interaction with human beings, devices, and the internet in real-time. This metauniverse sport interactive system is consistent with a self-powered anaerobic power meter (APM), a wireless transmission module, personalized data analysis based on the professional Wingate anaerobic power test method, and an augmented reality (AR) application. Self-powered APM is integrated with the axles of the bicycle to monitor human exercises, such as peak power (PP), mean power (MP), and fatigue index (FI). The data is transmitted to the cloud by the wireless transmission module and users can freely explore the metauniverse through the AR application. As a result of machine learning, the professional Wingate anaerobic power test method can not only reflect the anaerobic capacity, but also be used for athlete selection. This work provides a new approach to online competitions, sport training, and athlete selection and provides a new way to build metauniverse.
