Advanced Science, EarlyView.This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Wireless power transfer versus wireless information transfer
2012 IEEE/MTT-S International Microwave Symposium Digest, 2012Currently, there is not only a great need for power harvesting but also in many cases it is necessary to send information along with power over the same channel like in a RFID scenario. The goal of this paper is to illustrate that these objectives of simultaneous power transfer and information transfer are contradictory and a balance must be reached ...

This chapter introduces the fundamentals of wireless power transfer with an emphasis on implant powering . Firstly, an overview of implant powering solutions is introduced, and then, the decision of using wireless power transfer is justified. Next, among possible wireless power transfer methods, it is explained that why magnetic coupling befits the ...

Wireless power transfer (Wireless lighting)
2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA), 2015Wireless power transfer is a new technology to transfer electrical power without any physical contact between the source and the load. The aim of this paper is to propose the use of a simple, cheap and easy technique for mid range wireless power transfer.

Wireless Power Transfer—An Overview
IEEE Transactions on Industrial Electronics, 2019Due to limitations of low power density, high cost, heavy weight, etc., the development and application of battery-powered devices are facing with unprecedented technical challenges. As a novel pattern of energization, the wireless power transfer (WPT) offers a band new way to the energy acquisition for electric-driven devices, thus alleviating the ...

Wireless power transfer guides
2013 Asia-Pacific Microwave Conference Proceedings (APMC), 2013It is experimentally studied that the power transfer efficiency is improved by inserting a proper structure made of dielectrics, magnetic materials or metals between two spiral coils constituting a coupled-resonator WPT (Wireless power transfer) system. The structures can be hollow/solid circular cylinder, plate or rectangular parallelepiped. The power

2012 International Conference on Applied and Theoretical Electricity (ICATE), 2012
The paper is a general survey on power transfer by induction. The physical principle is pointed out and the constraints for an optimal operation applied both to the emitter and receiver are specified. Couple mode theory is used to study the wireless power transfer and a comparison with the circuit theory results is made.

Hybrid wireless power transfer
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017Both magnetic field and electric field can be used for transferring power wirelessly. But the up-to-date researches on wireless power transfer have been either inductive power transfer (magnetic field) or capacitive power transfer (electric field). An improved power transfer mode called hybrid wireless power transfer (HWPT) is proposed and evaluated in

Investigating wireless power transfer
Physics Education, 2017Understanding Physics is a great end in itself, but is also crucial to keep pace with developments in modern technology. Wireless power transfer, known to many only as a means to charge electric toothbrushes, will soon be commonplace in charging phones, electric cars and implanted medical devices.
