Fabrication and Characterization of an Ultra-High Current Electromagnetic Nanogenerator for Enhanced Energy Harvesting and Wireless Power Transmission Applications
Author :
Abstract
Electromagnetic Nanogenerator is one of the prominent candidates for harvesting renewable energy, exhibiting significant advantages. This type of nanogenerator can effectively convert energy from rotational movement to electricity based on electromagnetic induction. Herein, the fabrication of an Ultra-High Current Electromagnetic Nanogenerator (UHC-EMG) is reported and the electrical characterization results are fully investigated. The nanogenerator consists of 4 NdFeB magnets and coils to provide a high magnetic field. Under 1000 RPM the UHC-EMG can produce the output power of 348 W/m2(140 mW), an open circuit voltage of 2.4 V (Peak to Peak), and a high short circuit current of 432 mA. Also, the nanogenerator performance for charging different capacitors (1, 10, 22, and 33µF) is analyzed. Furthermore, in this paper, the ability of the nanogenerator for wireless power transmission is investigated which represents the eligibility of the UHC-EMG applications for the power supply of low-power electronic devices in different conditions.
