Abstract-Wireless charging is a technology of transmitting power through an air gap to electrical devices for the purpose of energy replenishment. The recent progress in wireless charging techniques and development of commercial products have provided a promising alternative way to address the energy bottleneck of conventionally portable battery-powered devices. However, the incorporation of wireless charging into the existing wireless communication systems also brings along a series of challenging issues with regard to implementation, scheduling, and power management. In this article, we present a comprehensive overview of wireless charging techniques, the developments in technical standards, and their recent advances in network applications. In particular, with regard to network applications, we review the static charger scheduling strategies, mobile charger dispatch strategies and wireless charger deployment strategies. Additionally, we discuss open issues and challenges in implementing wireless charging technologies. Finally, we envision some practical future network applications of wireless charging.

This paper focuses on wireless transfer power system based on Witricity technology, for resonant magnetic coupling and overviews the modeling of the coreless transformer used in the wireless system. An outline of a practical method is developed to calculate the system characteristic. An iterative process is carried out in order to find the parameter that optimizes the efficiency while minimizing the voltage across the resonant capacitors. The best modeling is the one giving the required power with the suited dimensioning and geometry. Four basic algorithms have been presented based on the impact of the issues of misalignment between the transmitter and the receiver including lateral displacement and angular tilt of the Witricity coils on the efficiency and used to detect and correct the power transfer efficiency optimization problem.

This paper describes the design, implementation and testing of a wireless blood pressure sensing implant. The implant is mounted on a stent graft. The implant along with the stent graft must fit into a 16F applicator stent delivery system. The implant is powered using the energy harvested from wireless power transmission. The measured pressure data is sent wirelessly to an external data reader hardware. The pressure measurement must have resolution of 1 mmHg.
