NFC-Enabled Batteryless AI-Integrated Sensing Network for Smart PPE System

In this manuscript, we explore the advancement in personal protective equipment (PPE), underscored by the rapid development in nanotechnology and smart systems. Our focus is on the development of an AI-integrated, batteryless, PPE system, tailored for high-risk occupational environments. This system represents a leap in smart PPE, capable of real-time sensing of six sensing parameters, incorporating near-field communication (NFC) technology for improved data exchange and system integration. Central to our approach is the use of nonintrusive sensing and communication technology, aimed at bolstering workplace safety without interfering with the operational capabilities of the wearer. The integration of multiple sensors on a batteryless smart PPE is challenged by power requirements, encouraging us to develop a multiantenna system that can monitor gas parameters at various locations of the PPE. We aim to provide a foundation for the future development of smart PPE that can withstand extreme environments while offering advanced functionality. The performance of the NFC-enabled smart PPE system is thoroughly validated through its integration into a full-face helmet, demonstrating its practical application and advanced sensing capabilities.
