As industries need more real-time monitoring and interconnected systems, the demand for wireless sensors expands. Vibrational energy harvesters are a potential solution for powering these sensors, as vibrations commonly exist where monitoring occurs. Developments in low-power circuitry have also led to the feasibility of these types of harvesters. Electromagnetic harvesters are a standout among various types of vibrational harvesters due to their ability to capture kinetic energy in a low-frequency range. This leads to these devices being more applicable in real-world applications where ambient vibrations are typical of having low frequencies. Hence, extensive research has been undertaken to make electromagnetic harvesters more efficient and compact. This review study aims to examine recent literature that has made advancements and demonstrated the full potential of such devices.
随着各行业对实时监测和互联系统的需求增加，对无线传感器的需求也在扩大。振动能量采集器是为这些传感器供电的一种潜在解决方案，因为在进行监测的地方通常存在振动。低功耗电路的发展也使这类采集器成为可能。电磁采集器在各种类型的振动采集器中表现突出，因为它们能够在低频范围内捕获动能。这使得这些设备在环境振动通常为低频的实际应用中更适用。因此，人们进行了广泛的研究，以使电磁采集器更高效、更紧凑。本综述研究旨在审视近期取得进展并展示此类设备全部潜力的文献。
