Wireless power transmission: R&D activities within europe

Abstract

Wireless Power Transmission (WPT) is an emerging technology that is gaining increased visibility in recent years. Efficient WPT circuits, systems and strategies can address a large group of applications spanning from battery-less systems, batteryfree sensors, passive Radio Frequency Identification (RFID), Near Field Communications (NFC) and many others. WPT is a fundamental enabling technology of the Internet of Things (IoT) concept, as well as Machine-to-Machine (M2M) communications, since it minimizes the use of batteries and eliminates wired power connections. WPT technology brings together RF and DC circuit and system designers with different backgrounds on circuit design, novel materials and applications and regulatory issues, forming a cross disciplinary team in order to achieve an efficient transmission of power over the air interface. This paper aims to present WPT technology in an integrated way, addressing stateof- the-art and challenges, and to discuss future R&D perspectives summarizing recent activities in Europ
