3. * INTRODUCTION :-
ʘ In this project we are generating energy as non conventional
source thorough walking or footstep.
ʘ Walking is the most common activity in our life.
ʘ As a person walks he/she releases an energy, this energy can
be stored and used as an electrical energy.
ʘ The main principal of this project is based on piezoelectricity
or piezo-electric effect.

5. WHAT IS PIEZO-
ELECTRIC
TRANSDUCER?
ʘ The prefix piezo- is a Greek
word which means to 'press' or
'squeeze'.
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.

6. Piezoelectric Sensor
Piezoelectric Sensor :-
ʘ A piezoelectric sensor is an electric device which
is used to measure acceleration, pressure, or force
to convert them to an electric signal. These
sensors are mainly used for process control,
quality assurance, research and development in
various industries. The applications of this sensor
involve, aerospace, medical, nuclear
instrumentation, and as a pressure sensor it is
used in the touch pad of mobile phones. In the
automotive industry, these sensors are used to
monitor ignition when developing internal
burning engines.

7. WHAT IS PIEZO-
ELECTRIC
EFFECT?
ʘ Piezoelectric Effect is the
ability of certain materials to
generate an electric charge in
response to applied mechanical
stress

8. * HOW IT WORKS :-
ʘ The proposed system works as a medium to generate power using force. ...
Whenever force is applied on piezoelectric sensor, then the force is converted
into electrical energy.
The system allows for a platform for placing footsteps. The peizo sensors are
mounted below the platform to generate voltage from footsteps.The sensors are
placed in such an arrangement so as to generate maximum output voltage. This is
then provided to our monitoring circuitry. The circuit is a microcontroller based
monitoring circuit that allows user to monitor the voltage and charges a connected
battery by it.
It also displays the charge generated and displays on an LCD display. Also it consists
of a USB mobile phone charging point where user may connect cables to charge
mobile phone from the battery charge. Thus we charge a battery using power from
user footsteps, display it on lcd using microcontroller circuit and allow for mobile
charging through the setup.
