摘要
随着低功耗无线传感网络和微机电系统的迅速发展,供电问题正成为它们进入实用化、产业化的一大障碍。现有的一个解决方案是微型电磁式振动能量采集器。首先给出电磁式振动能量采集器的工作原理、物理模型和设计原则,然后详细介绍目前国内外各研究小组研制的电磁式振动能量采集器的几何模型、结构参数、输出结果和技术特点,最后简单分析电磁式振动能量采集器面临的困难、挑战和发展趋势。
With the fast developments of low power wireless sensor networks and microelectromechanical system, energy supply is becoming a big barrier to their applications in engineering. Now a solution is to use microelectromagnetic vibration energy harvesters. The principle, physical model and design rule of electromagnetic vibration energy harvesters are presented. Geometric model, structural parameters, output results and technical characteristics of various electromagnetic vibration energy harvesters are analyzed. Finally, the difficulty and the challenge faced by us to develop electromagnetic vibration energy harvesters are discussed, and the development trend is pointed out.
