Power Generation from Footsteps by Using Piezoelectric Sensor

Abstract

Day by day the use of electricity has been increasing, hence it is necessary to generate electricity using a nonconventional system for conserving natural resources. Here we propose an advanced power generation system using footsteps. The system consists of piezoelectric sensors, Arduino UNO, LCD Display, PIC microcontroller, voltage boosters, battery, LDR and a socket for mobile charging. When the footstep pressure is applied on the piezoelectric sensor, it generates voltage, which in further generates electrical power. The sensors are placed in such an arrangement so as to generate maximum output of voltage. This is then provided to our monitoring circuit. By using this system, maximum voltage obtained is 22 Volt per step and minimum 1 Volt per step. By observing the footsteps at railway station, the power generated by piezoelectric sensor in 24 hours is approx. 78.4Volts.
