Multi-functional triboelectric nanogenerators on printed circuit board for metaverse sport interactive system

Abstract

Metaverse is the society of future, which merges the physical and digital worlds by utilizing sophisticated human-machine interfaces (HMIs). In this study, a Metaverse sport interactive system based on triboelectric nanogenerators has been developed, which realizes a real-time interaction among human beings, devices, and the internet. This Metaverse sport interactive system is composed of a self-powered anaerobic power meter (APM), a wireless transmission module, personalized data analysis based on the professional Wingate anaerobic test (WAnT) method, and an augmented reality (AR) application. By leveraging the WAnT method, the power (PP), mean power (MP), and fatigue index (FI) are tested, which indeed reflect the explosive power, speed endurance, and endurance. Meanwhile, the data is transmitted to the cloud via the wireless transmission module, and the users can freely explore the Metaverse through AR application. Notably, through machine learning, the professional WAnT can not only reflect the anaerobic capacity but can also be used for athlete selection. Essentially, this work puts forward a new approach to design online competitions, sport training, and athlete selection, and in general, provides a new strategy to build the Metaverse.
