THE FABRICATION OF AN IMPROVED PIEZOELECTRIC CHARGER
Abstract
This work is on foot step power generation using piezoelectric sensors. The demand for electrical energy is increasing day by day. But power generation conventional resources are now not enough for total demand of electrical energy. This device is designed to convert foot step, walking and running energy into electrical energy.
This paper demonstrates the method of harvesting energy from human walk. Generated electrical energy can be used to power mobile phones, emergency flashlights. It is based on a considerably designed structure of piezo transducers with a suitable thickness and diameter, which makes it easy-to use and accordant with a shoe sole. When pressure is applied on piezoelectric discs, AC voltage is produced which is then converted for desired output. After receiving desired outcomes, this energy source can become a direct current (DC) power supply with support from power management circuits. This energy can be stored in any external power storage.
