Intelligent Energy Harvesting and Magnet Induction for Mobile Phone Charging

Abstract

In this paper, we introduce an innovative piezoelectric material designed for efficient energy harvesting and charging of mobile phone batteries. This system offers intelligent control of the power generated from external excitation. A novel alloy has been built with advanced properties such as transparency and flexibility. The chemical composition contains mostly SiO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>, ZnO, and Pb(C<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>H<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>O<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>)<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>. Thereon, the result is an efficient piezoelectric material that permits to harvest as possible the energy due to the applied mechanical force. Furthermore, the system incorporates an appropriate rectifier and amplifier circuit to efficiently store the harvested energy in a mobile phone battery. Additionally, the system is boosted with a magnet induction to ensure a powerful energy source. The proposed hybrid system effectively meets the charging requirements of mobile phone batteries. To validate the functionality of the system, we integrated it into a sample shoe, connected it to a phone battery, and conducted real-time measurements in parallel. The system demonstrated satisfactory performance and met the required specifications. This study highlights the adaptability of our innovative system to various phone battery models, showcasing its high efficiency and potential as a promising alternative for mobile phone charging.
