This document describes a system for generating electricity from footstep power. The system uses piezoelectric sensors beneath footstep platforms to convert the kinetic energy from footsteps into electrical energy, which is stored in a lead-acid battery. An inverter then converts the DC battery voltage to AC voltage that can power various loads. The system has applications for powering lights and devices in areas with high foot traffic like streets, railways, temples, and more. It provides a renewable source of energy from an untapped resource of human footsteps.

3. INTRODUCTION
Walking is the most common activity in human
life.
When a person walks, he loses energy to the
road.
This energy can be tapped and converted in the
usable form such as in electrical form.

4. AN ALTERNATIVE ENERGY
SOURCE
 Footsteps are an
untapped natural
resource.
 The Challenge – convert
footstep energy to
electrical energy.
 The Solution – using
piezoelectric material.

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. PIEZOELECTRIC SENSOR
 A piezoelectric
sensor is a device that
uses the piezoelectric
effect to
measure pressure, accele
ration, strain or force by
converting them to
an electrical signal.

10. INVERTER
 An inverter is an electronic
device that converts direct
current (DC) to alternating
current (AC).
 The input voltage, output
voltage and frequency, and
overall power handling
depend on the design of the
specific device.

11. LEAD ACID BATTERY
Specifications
12V 1.3Ah sealed lead acid battery
1. high quality and high reliability.
2. maintenance free .
3. long life cycle.

12. WORKING
 When ever force is applied on piezo electric crystals
that force is converted to Electrical energy is used to
drive DC loads.
 Minute voltage Which is stored in the Lead Acid
battery. The battery is connected to the inverter.
 This inverter is used to convert the 12 Volt D.C to
the 230 Volt A.C. This 230 Volt A.C voltage is used to
activate the loads.

13. APPLICATIONS
 Foot step generated power can be used for agricultural,
home applications, street-lighting.
 Foot step power generation can be used in emergency
power failure situations.

14. ADVANTAGES
• Power generation is simply walking on step.
• No need fuel input.
• This is a Non-conventional system.
• Power also generated by running.
• Battery is used to store the generated power.

15. DISADVANTAGES
 Only applicable for the particular place.
 Initial cost of this arrangement is high.
 Mechanical moving part is high.
 Care should be taken for batteries.

16.  In concluding the words of our project, since the power generation using foot
step get its energy requirements from the Non-renewable source of energy.
 It is very useful to the places all roads and as well as all kind of foot step
which is used to generate the non conventional energy like electricity.
 It is able to extend this project by using same arrangement and construct in
the foot steps/speed breaker so that increase the power production rate by
fixing school and colleges, highways etc.
