Smart Piezoelectric Footstep Power Generation System – 5×2 Sensor Grid Renewable Energy Project Kit with LCD and Battery Charging

Description

⚙️ Project Overview

The Smart Piezoelectric Footstep Power Generation System is a modern renewable energy prototype that transforms the mechanical pressure of walking into usable electrical power.
The system consists of a 5×2 array of piezoelectric sensors (10 sensors total) arranged under a platform or tile surface.

When pressure is applied through foot movement, each piezo sensor produces an alternating current (AC) voltage.
This generated energy passes through a bridge rectifier and filter circuit to convert it into DC voltage, which is then stored in a 6V rechargeable lead-acid battery.

An LCD display monitors the real-time voltage level, while a connected LED circuit visually demonstrates power output.
This compact system is ideal for learning renewable energy concepts, power conversion, and practical energy harvesting applications.

⚡ Working Principle

The system operates based on the piezoelectric effect, where specific materials generate electrical potential when subjected to mechanical stress.

1. Energy Generation:
   As someone steps on the tile, pressure is applied to the 5×2 piezo sensor grid, producing alternating voltage pulses.

2. Rectification:
   The generated AC voltage from the piezo sensors is passed through a bridge rectifier to convert it into DC voltage.

3. Filtering and Storage:
   The DC output is filtered using capacitors to smooth voltage ripples and stored in a 6V lead-acid battery.

4. Display and Output:
   The LCD module shows the generated voltage level, while the LED circuit lights up to indicate usable energy output.

This self-sustained system highlights how human kinetic energy can be harvested and reused effectively.
