This document presents a footstep power generation system that uses piezoelectric materials to convert the mechanical energy from human footsteps into electrical energy. It discusses the components required, including piezoelectric crystals, batteries, capacitors, and an inverter. The working principle is that piezoelectric materials generate a charge when pressure is applied, allowing the system to harness energy from walking. Applications include powering lights and devices in areas with foot traffic like schools, malls, and metro stations. The system has advantages of being eco-friendly and self-generating, but high initial costs and limited applicability in only one location.

3. INTRODUCTION
It has the ability to produce electric power from mechanical force and
then it change to electric charges. Design concept used in this thesis is
to use piezoelectric place at the walking area named as "Foot Step
Power Generation System". When a human walking, jumping or
dancing on the surface which contain the piezoelectric, it then will
produce sufficient force for energy generation process.

5. PIZZOELECTRIC SENSOR
 A piezoelectric sensor is a device
that uses the piezoelectric effect to
measure changes in pressure,
acceleration temperature strain or
force by converting them to an
electrical charge.
 The prefix Piezo- is Greek for 'press'
or 'squeeze'

6. INVERTER
 A power inverter, or inverter, is an electronic device or circuitry
that changes 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 or circuitry.

9. Working principle
 The piezoelectric material
converts the pressure applied to
it into electrical energy.
 The source of pressure can be
either from the weight of the
moving vehicles or from the
weight of the people walking
over it.
 The output of the piezoelectric
material is not a steady one. So a
bridge circuit is used to convert
this variable voltage into a linear
one.

12. APPLICATION
Power generation using foot step can be used in most of the places such as
 Foot step generated power can be used for agriculture, home application, street
lightning.
 It can be used in emergency power failure situations.
 Application in Metros, rural area’s etc.
 colleges,
 Schools,
 Cinema theatres,
 Shopping complex and
 Many other buildings.

13. ADVANTAGE & DISADVANTAGE
ADVANTAGE
 Ecofriendly
 Self generating-no external power required
 Great variety of models available for any purpose
DISADVANTAGE
 Only applicable in the particular place.
 Mechanical moving parts are high
 The initial cost of this arrangement is high.
 Care should be taken for batteries

14. FUTUR ASPECTS
 We can use this principle in railway station, hospital, bank,
highway where vehicle rush too much.
 If we use this project at very busy stairs, then we produce
efficient electrical energy for large purpose.

15. CONCLUSION
 This can be used for many application in rural areas where power
availability is less or totally absence.
 As India is developing country where energy management is very big
challenge for huge population. By using this project we can drive both ac
and dc loads according to force applied on the piezo- electric sensor.
