In this paper, a novel approach of wireless power transfer (WPT) to microchip implanted in complex and (or) time-varying inhomogeneous environment has been proposed. This approach, based on the near field focus (NFF) and the principle of reciprocity, has been used to transfer electromagnetic energy efficiently by adaptive focus of the field. A numerical model of WPT, including transmit multiple antennas...
This paper mainly proposes an improved design of a wireless keyboard system by analyzing the hardware characteristics of each of its modules with the goal of reducing the power consumption of the wireless keyboard. In our experiment we have set the wireless keyboard at a fixed active voltage of 2.2 V with the lowest possible current consumption. The system can extend the working hours by 1.94 times...
