Introduction
 Now a days, electricity has become a need of every single human, demand of
electricity increasing day by day.
 This new generation needs lots of electrical power for their different
operations. There are various ways to generate electricity.
 The use of piezo-electric crystal is to produce the electric output from
surroundingvibrations.
 These materials have the ability to absorb mechanical energy from their
surroundings.
 usually ambient vibration and transform it into electrical energy that can be
used to power otherdevices.
Piezoelectric transducer
 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.
 Again an AC ripple filter is used to filter out any further
fluctuations in the output.
 The output dc voltage is then stored in a rechargeable battery.
Working
Working of piezo electric sensor
Power generation in footsteps by Piezoelectric materials
In a survey Israel is
putting PEG 6cmunder the road
level and at a distance of 30cm
apart. From this trial, it has been
seen that a vehicle weighing at
around 5 tons can generate
2000V, and a 1Km cluster of
such generator can generate
400Kwh energy. If 600vehicles
are allowed to go through this
road for an hour, it can power up
to 600-800 homes
Applications
Roads, highways and railways
This is the important
place which is responsible for
generation of large energy as
the huge amount of pressure is
exerted by crowd on the
footpaths. The embedded
piezoelectric crystals at the
footpaths & steps where people
make contact with the footpath
and these materials get
excessive pressure and force,
because of this greater amount
of energy is stored.
Power Generating in foot steps
Platforms / Footpath is most
common place on where we embed
the piezoelectric tiles to produce
the small amount of energy by
utilizing the human footstep over it.
The produced charge is stored in
battery and then that stored charge
can be use for charging low power
electronic devices.
Power Generating from Platforms
 It is eco friendly and produce no pollution to environment.
 Light weight and is easy to operate.
 Manufacturing cost is less and hence it proves to be economical.
 Piezoelectric transducers can be obtained in larger sizes.
Advantages
 Since the transducer material is delicate, it needs to be
handled carefully.
 As the voltage produced is less, additional equipments are
needed for the working.
Disadvantages

  • 10. Platforms / Footpath is most common place on where we embed the piezoelectric tiles to produce the small amount of energy by utilizing the human footstep over it. The produced charge is stored in battery and then that stored charge can be use for charging low power electronic devices. Power Generating from Platforms
  • 11.  It is eco friendly and produce no pollution to environment.  Light weight and is easy to operate.  Manufacturing cost is less and hence it proves to be economical.  Piezoelectric transducers can be obtained in larger sizes. Advantages
  • 12.  Since the transducer material is delicate, it needs to be handled carefully.  As the voltage produced is less, additional equipments are needed for the working. Disadvantages
