Abstract

Due to the low energy density of the electric field around the 220V power line, the energy harvester cannot directly drive the wireless sensor node (WSN). In order to ensure the work of WSN, this paper presents a self-switching energy management circuit that can control the charging and discharging of the storage capacitor and stable voltage output. Experimental results show that, with the help of the electric field energy harvester based on double-layer copper foil electrodes, the process of repeated charging and discharging is realized and the conversion efficiency is up to 60.9%.The low-power WSN is successfully driven for 880ms in the test.
