Wireless power transfer (WPT) plays an increasingly important role in internet of things (IoTs) and biomedical applications. With the rapid development of 5G and IoTs, the dense deployment of sensor nodes and heterogeneous integration of sensor network become more and more popular. An easy access to power with the least dependence on power storage system (battery) is highly desirable. To address the power hunger of sensor nodes, WPT technology plays an important role. On the other hand, numerous applications in medical diagnostics and therapeutics ranging from cardiac pacemakers to emerging devices in visual prosthesis, brain computer interfaces and body area networks have spurred electronic engineers to propose new wireless medical devices. Wireless implantable medical devices (IMDs) provide an opportunity to improve the patient health monitoring and treatment. To facilitate the miniaturization of IMDs and to extend the lifespan without incorporating a bulky battery, the wireless power transfer (WPT) technology plays an essential role. In this presentation, various wireless power approaches used for IoTs and biomedical applications will be introduced. Our recent research progress on WPT will be presented. Examples on near-field inductive and capacitive wireless power and far-field wireless power will be given.
