This document describes a system for generating electricity from footstep power using a piezoelectric sensor and microcontroller. The system works by converting the downward force of a footstep on a plate into rotational motion of a shaft connected to a generator. When a person steps on the plate, the piezoelectric sensor produces electricity that is stored in a battery. The stored power can then be used for applications like street lights, fans, or security alarms. The system provides an alternative renewable energy source and has potential to harness wasted foot traffic energy in crowded areas.

3. POWER GENERATION THROUGH
FOOT STEPS

4. > For an alternative method to generate electricity there
are number of methods by which electricity can be
produced.
> Out of such methods, foot step energy generation can be
an effective method to generate electricity.
INTRODUCTION

5. NEED OF THE SYSTEM
The utilization of waste energy of foot power with
human motion is very important for highly populated
countries.
India and China where the roads, railway stations,
temples, etc. are all over crowded and millions of people
move around the clock.

6. BASIC PRINCIPLE
When a pedestrian steps on the top plate of the device,
the plate will dip down slightly.
The downward movement of the plate results in
rotation of the shaft of an electrical alternator fitted in the
device.

9. WORKING
The pushing power is converted into electricity
The piezoelectric material is fixed at the plane.
The spring is used to return the inclined step in same
position by releasing the load.
The shaft of generator is connected to the piezoelectric
material. DC is generated.

10.  To store the electricity in battery.
 Easy construction.
 Less number of parts required.
 Electricity can used for many purposes.
ADVANTAGES

11. DISADVANTAGES
Only applicable for the particular place.
Initial cost of this arrangement is high.
Tiles used are durable but not everlasting.

12.  In street light.
 In LED light for specific purposes.
 In air circulation system for room by the small fans.
 For used in security alarm.
 Also implement in DJ floor.
APPLICATION

13. > > We can use this principal in the speed breakers at high
ways , where the vehicles rush too much, thus increase input
torque and ultimate output of generator.
> > If we use this project at very busy stairs , then we
produce efficient useful electrical energy for large purposes
.
FUTURE ASPECTS

14. Expected Result & Discussion
Output power
Let,
Mass of pedestrian = 65 kg
Distance travelled by plate = 10 cm
So, work done on plate by impact
= weight of body * distance
= 65 * 9.81*0.1 Nm
= 63.765 J
So, power output
=work done/sec
=63.765/60 Watts
=1.06275 Watts
This much power is generated just by one foot step.
