Abstract

This research proposes a rotary motion-based non-contact pendulum piezoelectric energy harvester (P-PEH). The working region of the piezoelectric vibrator can be maintained in a magnetically coupled system at all times by means of a motion conversion mechanism. The combination of the motion conversion mechanism and the magnetic coupling system not only reduces the loss of the piezoelectric material, but also improves the output performance of the piezoelectric vibrator. The paper investigates the effects of the excitation distance L, the radius of the base circle R, and the number of excitation magnets N on the output performance of the P-PEH. When the input speed of 600 rpm, L = 10 mm, R = 21 mm, and N = 1, the peak-to-peak voltage (Vpp) is 58.75 V. At this parameter, the output power of the device with an external 20 kΩ load is 0.0187 W. The viability of P-PEH was finally demonstrated through several application testing. P-PEH can easily light up 63 LEDs while its output energy can keep the temperature and humidity sensor in use. In summary, P-PEH can effectively collect external rotational energy for power storage and supply, and supply electricity to wireless sensor networks and microelectronic devices with further studies.

摆式磁耦合旋转压电能量收集器

本研究提出了一种基于旋转运动的非接触摆式压电能量收集器（P-PEH）。通过运动转换机构，压电振动器的工作区域可始终保持在磁耦合系统中。运动转换机构与磁耦合系统的结合不仅减少了压电材料的损耗，还提高了压电振动器的输出性能。本文研究了激振距离 L、基圆半径 R 和激振磁体数量 N 对 P-PEH 输出性能的影响。当输入转速为 600 rpm、L = 10 mm、R = 21 mm、N = 1 时，峰峰值电压 (Vpp) 为 58.75 V。P-PEH 可以轻松点亮 63 个 LED，同时其输出能量可以保证温湿度传感器的正常使用。总之，P-PEH 可以有效地收集外部旋转能量进行电力存储和供应，并通过进一步研究为无线传感器网络和微电子设备供电。

期刊介绍： Smart Materials and Structures (SMS) is a multi-disciplinary engineering journal that explores the creation and utilization of novel forms of transduction. It is a leading journal in the area of smart materials and structures, publishing the most important results from different regions of the world, largely from Asia, Europe and North America. The results may be as disparate as the development of new materials and active composite systems, derived using theoretical predictions to complex structural systems, which generate new capabilities by incorporating enabling new smart material transducers. The theoretical predictions are usually accompanied with experimental verification, characterizing the performance of new structures and devices. These systems are examined from the nanoscale to the macroscopic. SMS has a Board of Associate Editors who are specialists in a multitude of areas, ensuring that reviews are fast, fair and performed by experts in all sub-disciplines of smart materials, systems and structures. A smart material is defined as any material that is capable of being controlled such that its response and properties change under a stimulus. A smart structure or system is capable of reacting to stimuli or the environment in a prescribed manner. SMS is committed to understanding, expanding and dissemination of knowledge in this subject matter.
