The aim of this work is to demonstrate the feasibility use of an Micro air vehicles (MAV) in order to power wirelessly an electric system, for example, a sensor network, using low-cost and open-source elements. To achieve this objective, an inductive system has been modelled and validated to power wirelessly a sensor node using a Crazyflie 2.0 as MAV. The design of the inductive system must be small and light enough to fulfil the requirements of the Crazyflie. An inductive model based on two resonant coils is presented. Several coils are defined to be tested using the most suitable resonant configuration. Measurements are performed to validate the model and to select the most suitable coil. While attempting to minimize the weight at transmitter’s side, on the receiver side it is intended to efficiently acquire and manage the power obtained from the transmitter. In order to prove its feasibility, a temperature sensor node is used as demonstrator. The experiment results show successfully energy transportation by MAV, and wireless power transfer for the resonant configuration, being able to completely charge the node battery and to power the temperature sensor.

用于无线电力传输系统的微型飞行器能量传输

这项工作的目的是展示微型飞行器 (MAV) 的可行性，以便使用低成本和开源元件为电气系统（例如传感器网络）无线供电。为实现这一目标，我们对感应系统进行了建模和验证，以使用 Crazyflie 2.0 作为 MAV 为传感器节点无线供电。感应系统的设计必须足够小和轻，以满足 Crazyflie 的要求。提出了基于两个谐振线圈的电感模型。几个线圈被定义为使用最合适的谐振配置进行测试。执行测量以验证模型并选择最合适的线圈。在尝试将发射器侧的重量降至最低时，在接收器侧，它旨在有效地获取和管理从发射器获得的功率。为了证明其可行性，使用温度传感器节点作为演示器。实验结果表明，通过 MAV 成功传输能量，并为谐振配置进行无线电力传输，能够为节点电池完全充电并为温度传感器供电。
