Abstract

This paper presents a piezoelectric energy harvesting device with anti-interference capability. The device utilizes magnetic coupling between the magnet at the tip of the piezoelectric cantilever and the alternating magnetic field surrounding power lines to efficiently harvest energy. Three piezoelectric cantilever structures are designed to optimize energy harvesting efficiency and space utilization. The impact of magnet interaction on the energy harvesting performance is investigated through theoretical analysis and experiments. The results demonstrate a decrease in the natural frequency of each piezoelectric cantilever due to magnet interaction. Frequency compensation techniques are applied to improve the overall output of the device. The anti-interference capability of the harvester is thoroughly evaluated, showing stable output even under random acceleration and the ability to withstand external interference. Additionally, the device successfully powers a wireless temperature and humidity sensor, validating its potential for self-powered wireless sensing nodes in grid monitoring systems.
