Wireless power transfer versus wireless information transfer

2012 IEEE/MTT-S International Microwave Symposium Digest, 2012
Currently, 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 ...

A literature survey of wireless power transfer

2016 IEEE International Conference on Electro Information Technology (EIT), 2016
Over 115 years ago Tesla invented the concept of wireless power transfer. Many industrial applications based on this technology have been developed ever since. This technology is of interest especially where the interconnecting wires are inconvenient, or even impossible.

Wireless power transfer for a pacemaker application

Journal of Medical Engineering & Technology, 2017
An artificial pacemaker is a small medical device that uses electrical impulses, delivered by electrodes contracting the heart muscles, to regulate the beating of the heart. The pacemaker is implanted under the skin, and uses for many years regular non-rechargeable batteries.

Phased arrays in wireless power transfer

2017 IEEE 60th International Midwest Symposium on Circuits and Systems (MWSCAS), 2017
The recent increase in RFID usage coupled with the evolving IoT has revamped the need for Wireless Power Transfer (WPT). In this paper, a brief review of systems using WPT is offered including: RFIDs, inductively coupled systems and electromagnetic harvesters. A case study for phased array antenna beamforming and its benefits to wireless power transfer

Energy Encryption for Wireless Power Transfer

IEEE Transactions on Power Electronics, 2015
This paper presents a novel energy encryption strategy for wireless power transfer (WPT) systems, which can effectively improve the security performance of wirelessly transferred energy. In a WPT system, energy is expected to transfer to specific receptors as well as to switch off other unauthorized energy transmission channels, so the security of ...

Interference Analysis in Wireless Power Transfer

IEEE Communications Letters, 2017
This letter studies the effect of co-channel interference (CCI) generated by wireless power transfer on information delivery for three widely used setups, i.e., power beacon (PB), hybrid access point (HAP), and simultaneous wireless information and power transfer (SWIPT).
