Portable DC Regulated Power Supply from Footsteps

Due to the increasing modern day development conventional method of electricity generation is becoming insufficient and there is greater need for other mode of generating electrical energy. To compensate this crises Non- conventional energy source system is considered in our work. Walking is a day to day activity of a normal person where he/she loses energy to the surface while walking, in the form of impact, vibration, and sound. This loss of energy is due to the transfer of his weight onto the surface through foot falls on the ground during every step. This energy can be tapped and converted into usable electrical energy. The main aim of this project is to produce 5V, 9V and 12V power supply by a portable DC regulated power supply system. This is achieved through engineering a Piezo electric transducers attached with the shoe which converts pressure captured from each foot step to an electrical charge. This energy is stored and used as a power source with rechargeable battery which is amplified and regulated later to produce a constant supply.
