本文讨论了一种多向、通用的电磁能量采集器的研制。该装置是一个由两部分组成的球:一个刚性的球形核心,内部有管道,线圈和磁铁,以及一个柔性的硅基外壳,容纳载液。该设计的多方向性来自于器械的球形。当受到压缩力时,采集器通过使流体移动通过管、推动永磁球通过缠绕在管上的线圈来产生能量。使用3D打印的PLA塑料和模制硅胶的组合来生产原型。能量采集器可用于存在振荡压缩的应用中,并且由于其通用的球形形状而不限于某些应用。在其四个不同的外侧以4-15 Hz之间的五种不同频率进行测试,产生17至44 mV范围内的电流。
This paper discusses the development of a multi-directional, universal, electromagnetic energy harvester. The device is a ball consisting of two parts: a rigid spherical core with internal tubes, coils and magnets, and a flexible silicone-based shell holding a carrier fluid. The multi-directional aspect of the design comes from the device’s spherical shape. The harvester generates energy when subject to compressive force, by moving fluid through a tube, pushing a permanently magnetized ball through a coil wound around the tube. A combination of 3-D printed PLA plastic and molded silicone was used to produce a prototype. The energy harvester can be utilized in applications where there is an oscillating compression and it is not limited to certain applications due to its universal ball shape. It was tested at five different frequencies between 4–15 Hz on its four different outer sides producing electricity at a range of 17 to 44 mV.
