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.

赫特和特斯拉首先引入了动力传输原则。如今，无线电源传输（WPT）技术提供了剪断最后的电线，并允许用户以真正的空间自由度为设备充电设备，并且像通过空中传输数据一样容易。随着使用无线设备（即笔记本电脑，智能手机和可穿戴设备）的爆炸式增长，实时访问电源的需求不再是奢侈品，而是必要的，并且正在加剧WPT技术的需求。该跨学科研究计划旨在通过实时提供动力和否则无法访问的领域来解决自适应WPT和能量收获的需求。电感谐振和远程RF无线功率传输都将得到解决，以及新一代的集成自适应RF发电器。将首次将两种竞争性传输/收获技术（中等电感和远程RF）组合在一起，形成一个可重新配置和自适应的WPT系统。通过使用磁场强度和RF功率的范围和位置各不相同，使用主动超材料和可重新配置的磁浓缩器将通过抵消磁场强度和RF功率的损失来优化功率传输效率（PTE）。此外，拟议的新型功率收割机将具有双功能谐振线圈/低增生天线阵列的感应和RF功率接收能力，以形成电感界限以及基于超材料的基于RF的能量浓缩器和超级长度。中端感应共振剂WPT的应用包括下一代零发射电动汽车（EV）技术，医疗植入物，例如起搏器，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确实有望解锁空间自由，范围从5米到100米，没有电池，无电的无线传感器网络和应用程序，可能包括物联网（IoT），MMID和RFIDS，MMID和RFIDS，智能家庭，实时定位系统（RTLS），UAVS，UAVS，EAVESPACE和PACCASPACTIONS PLACESPACTINS PARCASSICTIONS。最后，动力收割机在智能家居，互联车辆，物联网，医疗传感器，遥测等中找到了应用。
