The principle of power transmission was first introduced by Hertz and Tesla. Today, Wireless Power Transfer (WPT) technology offers to cut the last cord and allow users to charge devices with true spatial freedom and as easily as data is transmitted through the air. With the explosion in the use of wireless devices, i.e. laptops, smartphones and wearables, the need for accessing power in real-time is no longer a luxury but rather a necessity and is fueling the need for WPT technology. This interdisciplinary research program seeks to address the need for adaptive WPT and energy harvesting by providing power on-the-go in real-time and to areas where it would be otherwise inaccessible. Both inductive resonant and long-range RF wireless power transfer will be addressed as well as a new generation of integrated adaptive RF power harvesters. For the first time, two competing power transmission/harvesting technologies, mid-range inductive and long range RF, will be combined to form a single reconfigurable and adaptive WPT system. The use of active metamaterials and reconfigurable magnetic concentrators will optimize Power Transmission Efficiency (PTE) by offsetting losses in magnetic field strength and RF power as range and location vary. In addition, the proposed novel power harvesters will feature both inductive and RF power reception capabilities with dual function resonant coil/low-gain antenna arrays to form inductive beamforming as well as metamaterial based RF energy concentrators and superlenses. Applications for mid-range inductive resonant WPT include next-generation zero-emission electric vehicle (EV) technology, medical implants such as pacemakers, non-invasive surgical devices, power tools, laptops, smartphones, UAVs and more. Long-range RF WPT truly promises to unlock spatial freedom to ranges from 5 meters to 100 meters with battery-less, self-powered wireless sensor networks and applications potentially include the Internet of Things (IoT), MMIDs and RFIDs, smart homes, Real-Time Localization Systems (RTLS), UAVs, aerospace and space applications where power is unavailable. Finally, power harvesters find applications in smart homes, connected vehicles, IoTs, medical sensors, telemetry and much more.**

电力传输原理最先由赫兹和特斯拉提出。如今，无线充电 (WPT) 技术可以切断最后一根电线，让用户能够真正自由地为设备充电，就像通过空气传输数据一样轻松。随着笔记本电脑、智能手机和可穿戴设备等无线设备的使用激增，实时获取电力的需求不再是一种奢侈，而是一种必需品，并且推动了对 WPT 技术的需求。这一跨学科研究项目旨在通过实时向无法到达的区域提供移动电源来满足自适应 WPT 和能量收集的需求。感应谐振和远程射频无线功率传输以及新一代集成自适应射频功率采集器都将得到解决。首次将两种相互竞争的电力传输/收集技术（中程感应式和远程射频）结合起来，形成单一的可重新配置和自适应 WPT 系统。使用活性超材料和可重构磁集中器将通过抵消磁场强度和射频功率随范围和位置变化而产生的损失来优化功率传输效率（PTE）。此外，所提出的新型功率采集器将具有感应和射频功率接收能力，具有双功能谐振线圈/低增益天线阵列，以形成感应波束形成以及基于超材料的射频能量集中器和超级透镜。中程感应谐振 WPT 的应用包括下一代零排放电动汽车 (EV) 技术、起搏器等医疗植入物、非侵入性手术设备、电动工具、笔记本电脑、智能手机、无人机等。远程 RF WPT 真正有望通过无电池、自供电无线传感器网络和应用程序（包括物联网 (IoT)、MMID 和 RFID、智能家居、Real 等）真正实现 5 米至 100 米范围内的空间自由。 - 无法供电的时间定位系统 (RTLS)、无人机、航空航天和太空应用。最后，电力采集器在智能家居、联网车辆、物联网、医疗传感器、遥测等领域得到应用。**
