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.
