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.chiggate.com/voyage-et-cie-5-3-wick-candle-discount/
