Abstract
Wireless power transmission is the process to transmit electrical energy without using wire or any physical link. WPT is mainly used at such places where it is difficult to transfer energy using conventional wires. In this research work, we investigated the need and feasibility of wireless power transmission for underwater applications. This research paper will outline research challenges, limitations and practical consideration for underwater wireless power transfer (UWPT). Recent researchers have focused on WPT in air. However, WPT is still a challenging task in underwater environment. In this study, we have presented a review on previous research works in underwater wireless power transfer (UWPT). We have provided a comparison of different techniques implemented for wireless power transfer. This paper also proposes the idea of MIMO wireless power transmission for AUVs charging. This paper elaborates capabilities and limitations of the wireless power transfer system in underwater media as stochastic nature of ocean is a big challenge in wireless power transmission. We have also addressed design challenges and seawater effects on UWPT system.

Summary
The ongoing research and fast-expanding market of electrical vehicles has reinvigorated the wireless power transfer (WPT) technology. A crucial need of WPT has emerged lately in distributed ocean systems which require excessive power such as ocean monitoring devices, sensor nodes, autonomous underwater vehicle (AUVs). These underwater devices are being used in innumerous underwater applications such as data collection, monitoring and underwater observation. The typical process to recharge these electronic devices is time-consuming which results into disrupted service and limited operation range To bridge these gaps, an extensive research work on AUVs is required. It requires high cost for maintenance and useful for near shore applications only These implementations can be used for specific missions such as SARS operations, oceanography studies, weather reporting and monitoring of water parameters. What is the effect of high conducting water medium on electrical parameters of WPT system?
