论文摘要
无电池传感器是可取的，因为它们会对要监视的系统或周围环境的操作产生可忽略的影响。无电池传感器的无线能量传输很具有挑战性，因为由于缺乏能量，它们无法与充电器配合。在本文中，开发了一种用于无均匀介质中无电的传感器的无线能量传输的磁性盲梁（MAGBB）算法。带有随机导向线圈的无电池传感器可能会遇到明显的方向损失，并且可能不会从充电器中获得任何能量。 MAGBB使用一组优化的电流向量生成旋转磁场，这些磁场可以确保具有任意取向的无电池传感器上的线圈可以接收足够的电压以充电。它不需要有关无电池传感器线圈方向或位置的任何信息。 MAGBB的效率通过广泛的数值模拟证明。
Tiny batteryless sensors are desirable since they create negligible impacts on the operation of the system being monitored or the surrounding environment. Wireless energy transfer for batteryless sensors is challenging since they cannot cooperate with the charger due to the lack of energy. In this paper, a Magnetic Blind Beamforming (MagBB) algorithm is developed for wireless energy transfer for batteryless sensors in inhomogeneous media. Batteryless sensors with randomly orientated coils may experience significant orientation losses and they may not receive any energy from the charger. MagBB uses a set of optimized current vectors to generate rotating magnetic fields which can ensure that coils on batteryless sensors with arbitrary orientations can receive sufficient voltages for charging. It does not require any information regarding the batteryless sensor's coil orientation or location. The efficiency of MagBB is proven by extensive numerical simulations.
