In this paper. we present a wireless sensor system (WSS) that integrated an inductive wireless power transfer (I-WPT) module for battery-free real-time monitoring of the status of rotating shaft in ships. Firstly. an optimized I-WPT module for seamless power supply was implemented using multiple Tx and Rx coils. https://www.bekindtopets.com/flash-find-Winmau-Firestorm-Steel-Tip-Darts-24gm-special-save/
