The document presents a proposal for generating power from footsteps on staircases using piezoelectric transducers. The system would convert the mechanical energy from footfalls on instrumented stair treads into electrical energy to power small loads like LED lights. It proposes installing the systems in locations with high foot traffic like train stations, airports, universities and stadiums to take advantage of renewable energy from human movement.

2. INTRODUCTION
Nowadays, energy and power are one of the basic necessities
regarding this modern world. As the demand of energy is
increasing day by day, so the ultimate solution to deal with these
sorts of problems is just to implement the renewable sources of
energy. With the decrease in energy consumption of the portable
electronic devices, the concept of harvesting renewable energy in
human surrounding arouses a renewed interest. The objective of
this work is power generation through footsteps as a source of
renewable energy that can be obtained while walking on to certain
arrangements like footpaths, stairs, platforms. This system can be
installed at homes, colleges, railway stations, where the people
move around the clock. The utilization of this energy from human
footsteps is very much relevant and important for populated
countries like India and China.

3.  “Low power consumption of electronic device.”
( It would be taken as an advantage and the system would
prefer usage of electronic systems.)
 “Mechanical energy generated while stepping the
stairs in the form of force acting on the stairs from
the foot.”
(This mechanical energy would be used to generate
electrical energy.)
Basic working factor:-

4. “Place of employment”:
 Basically the project would be set up in those areas
where the people move around the clock like railway
stations and airports, universities, stadiums etc.
 In the context of such a densely populated country like
India, China etc. it gains a significant meaning.

5. “Basic theory of project”
 Basically in our project we would employ
“piezoelectric transducers” which act as
electromechanical converter to convert the
produced mechanical energy into electrical energy
while stepping on the stairs.
---------------------------------------------------------------
 Keyword:- “Electromechanical converter”

6. Basic theory of “Piezoelectric
Generator”
 The piezoelectric generator basically consists of
piezoelectric material which generate electrical
energy when they are stressed by mechanical
vibrations produced upon stepping on the stairs.
This produced electrical charge is stored in the
battery (here we are using Nickel metal hydride
battery) which is the used to run the connected
load like light emitting diode (LED).

7. “Overview of Project Design”
 i) Moving Stair Tread
The moving stair would be assembled along with a base plate
such that it is hinged on one side to give a single degree of
freedom.
 ii) Piezo -Electric Material
It is employed between the moving stair tread and the base
plate such that it gets the mechanical vibrations from the
stairs.
 iii) LED or other Lightings
Light emitting diodes would be employed of sufficient rating
to satisfy the usage need.

8.  Basically the piezoelectric materials are special type of
materials which lie in the class of ferroelectrics.
 These material basically consist of significant number
of “Dipoles”
 The dipoles originate due to the local charge separation
in the crystal.
“Overview of Project
application”

9.  Piezoelectric effect.
It includes generation of electrical charge from thre applied mechanical
energy.
 Converse piezoelectric effect.
It includes production of mechanical strain under the application of
external field.
“Working domain of
piezo-electric materials”

10. “Piezoelectric Generator
Principle”
 The conversion chain starts with a mechanical energy
source: Staircase. Movement on the stairs produces
vibrations and they are converted into electicity via
piezoelectric element. The electricity produced is
thereafter formated by a static converter before supplying
a storage system or the load (electrical device).

11. “Proposed
electrical design”
. We will rectify the output of the Piezo Electric generator
and then send it to a small battery for storage. From here,
the energy can be used in any the user desires.It would be
ideal to power LED lights which consume small amounts of
power.

13. “Advantages”

 Harvest small, but still significant amounts of energy.

 An innovative approach to a device that people use every day.

 No compromise to safety or reliability.

 Marketing and appearance could encourage people to take the
stairs instead of energy intensive alternatives such as an
elevator or escalator.

14. “Product features”

 Electricity is generated through stepping on stair tread.

 Stairs tread returns to “up” position via springs.

 Power can be stored for a future use.

 Design will be expandable to several steps and several Piezo-
generators per step.

 Cost will be minimal to promote adoption.


15. “Future work”
 It will include use of:
 Microcontroller
 Sensor
 Lighting system
It would basically consists of light emitting diodes.
 Promotion of concept of “GREEN DESIGN”

16. “Cost analysis”
 The cost of the Piezo-electric generator may come
upto Rs.500 and the setup for the staircase was
designed by us. The NiMH battery is available in the
market for Rs.800 and the other circuits add upto Rs.
500. So the final budget for this project is around Rs.
1800.
