This paper reviews current research on piezoelectric energy harvesting devices for low-frequency applications (0- 100Hz). It explores the challenge of optimizing energy output due to the high elastic moduli of piezoelectric materials. Key aspects contributing to harvester performance are discussed, aiming to minimize reliance on external power and maintenance for devices like wireless sensor networks. Optimizing geometry and dimensions of piezoelectric elements enhances energy conversion efficiency by matching vibration frequencies. Efficient energy management circuits are crucial for capturing and storing harvested energy effectively. These circuits must be capable of efficiently converting the AC output of the piezoelectric harvester into a stable DC voltage suitable for powering electronic devices or charging energy storage devices such as batteries or capacitors. In addition to material and design considerations, environmental factors such as temperature variations and humidity levels can significantly impact the performance of piezoelectric energy harvesters. Therefore, robust encapsulation techniques must be employed to protect the harvester from adverse environmental conditions while ensuring long-term reliability. Overall, this paper provides insights into the current challenges and advancements in the field of piezoelectric energy harvesting for low-frequency applications, offering valuable perspectives for future research and development efforts in this area.
