Abstract

Ground-breaking optical wireless power transfer (OWPT) techniques have gained significant attention from both academia and industry in recent decades. Powering remote systems through laser diodes (LDs) to either operate devices or recharge batteries offers several benefits. Remote LDs can remove the burden of carrying extra batteries and can reduce mission time by removing battery swap-time and charging. Apart from its appealing benefits, laser power transfer (LPT) is still a challenging task due to its low transfer efficiency. In this paper, we discuss the necessity and feasibility of OWPT and discuss several projects, working principle, system design, and components. In addition, we show that OWPT is an essential element to supply power to Internet-of-Things (IoT) terminals. We also highlight the impacts of dynamic OWPT. We outline several OWPT techniques including optical beamforming, distributed laser charging (DLC), adaptive-DLC (ADLC), simultaneous lightwave information and power transfer (SLIPT), Thing-to-Thing (T2T) OWPT, and high intensity laser power beaming (HILPB). We also deal with laser selection, hazard analysis, and received photovoltaic (PV) cell selection for OWPT systems. Finally, we discuss a range of open challenges and counter measures. We believe that this review will be helpful in integrating research and eliminating technical uncertainties, thereby promoting progress and innovation in the development of OWPT technologies.

摘要

近几十年来, 开创性的光无线能量传输(OWPT)技术在学术界和业内专家中都得到广泛关注. 通过激光二极管(LDs)对操作设备或电池远程供电有很多优点. 远程LDs可以消除额外携带电池的负担, 同时可以通过减少电池更换与充电的时间来节省任务时间. 然而激光能量传输(LPT)除了具有吸引人的优点外, 因其传输效率低, 仍然是一项具有挑战性的任务. 此篇综述讨论了OWPT的必要性和可行性, 并讨论了其工作原理、 系统设计和组件等. 此外, 还表明了OWPT是为物联网(IoT)终端供电的必要部分, 强调了动态OWPT的影响. 本文概述了几种OWPT技术, 包括光波束赋形、 分布式激光充电(DLC)、 自适应分布式激光充电(ADLC)、 同步无线信息与功率传输(SLIPT)、 物对物(T2T)OWPT和高强度激光能量束(HILPB), 还论述了OWPT系统的激光选择、 危害分析和接收器太阳能电池的选择. 最后, 讨论了一系列公开挑战和应对措施. 我们相信, 此篇综述将有助于整合研究和消除技术不确定性, 从而促进OWPT技术发展的进步和创新.
