3. ABSTRACT
Man has needed and used energy at an increasing rate for the
substance and well -being since time immemorial. Due to this a lot
of energy resources have been exhausted and wasted. Proposal for
the utilization of waste energy of foot power with human
locomotion is very much relevant and important for highly
populated countries like India where the railway stations, temples,
etc., are overcrowded all round the clock.

4. OBJECTIVE
In this project we are converting Mechanical energy
into Electrical energy. We are trying to utilize the
wasted energy in a useful way. By using Rack and
Pinion arrangement we are converting to and from
motion of the steps into rotational motion of the
dynamo.

5. INTRODUCTION
In this topic we are generating electrical power as non-
conventional method by simply walking on footstep.
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.

6. 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.

8. CIRCUIT EXPLANATION
Step 1: Connect the piezoelectric sensor to the bridge rectifier using wires. The
positive and negative terminals of the sensor should be connected to the input
terminals of the bridge rectifier.
Step 2: Connect the output terminals of the bridge rectifier to a capacitor using
wires. The positive and negative terminals of the capacitor should be connected to
the positive and negative terminals of the bridge rectifier, respectively.
Step 3: Connect a resistor in parallel with the capacitor using wires. The resistor
should have a resistance value between 100 kΩ and 1 MΩ.
Step 4: Connect an LED in parallel with the resistor using wires. The anode of the
LED should be connected to the positive terminal of the capacitor, and the
cathode of the LED should be connected to the negative terminal of the resistor.

9. Step 5: Place the piezoelectric sensor on a surface where it can be stepped
on. When someone steps on the sensor, it will generate a mechanical
deformation, which will be converted into electrical energy by the
piezoelectric effect.
Step 6: The electrical energy generated by the piezoelectric sensor will be
rectified by the bridge rectifier and stored in the capacitor. The resistor will
limit the charging current of the capacitor, and the LED will indicate the
presence of electrical energy.
Step 7: When the capacitor is fully charged, the LED will light up, indicating
that there is electrical energy stored in the capacitor. The LED will remain lit
until the capacitor discharges completely.

11. When ever force is applied on piezo electric crystals that
force is converted to Electrical energy is used to drive DC
loads. And that 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.
We are using conventional battery charging unit also for
giving supply to the circuitry.

12. 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.
Metros, Rural Applications etc.

13. ADVANTAGES
Power generation is simply walking on step.
No need fuel input.
This is a Non-conventional system.
 No moving parts - long service life.
 Self-generating - no external power required.
Compact yet highly sensitive

14. CONCLUSION
In conclusion, footstep power generation using piezoelectric
sensors is a promising technology for harvesting energy from
human foot traffic. Piezoelectric sensors can generate
electricity by converting the mechanical energy produced by
footsteps into electrical energy. This technology has the
potential to be used in various applications, such as powering
low-power electronic devices in public places, remote areas,
or even in wearable devices.
