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.

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
The prefix Piezo- is Greek for 'press'

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.

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
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

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
It can be used in emergency power failure situations.
Application in Metros, rural area’s etc.
Shopping complex and
Many other buildings.

ADVANTAGE & DISADVANTAGE
Self generating-no external power required
Great variety of models available for any purpose
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

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.

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.
