3. Problem statement
 In Pakistan the demand is more than the daily energy
produced so we are facing power-cut after approximate 1 hour
and industries are in hell these days. People uses rechargeable
batteries (UPS) or diesel/petrol engine to fulfill their demands.
The use of stand by generator is common in industries and
large offices.We will generate electrical energy using
piezoelectric material (which convert Mechanical stress into
Electrical Energy) and will control the output with
microcontroller.

4. Brief Introduction
 This project is used to generate voltage using footstep force.
The proposed system works as a medium to generate power
using force. This project is very useful in public places like bus
stands, theaters, railway stations, shopping malls, etc.

5. Type of project

8. FYP Objective
 Human/bio-energy is being
wasted if it can be made possible
for utilization it will be great
invention and crowd energy farms
will be very useful energy sources
in crowded countries.
 Pollution less generation
 Noise less generation
 Fuel less

9. Calculations
 Let’s assume the 100 footsteps push the plate of piezo
electric transducer in 1 hour then the current produce is
 For 1 footstep current = 10mA
 100 footsteps current = 10*100
 =1000mA
 Produce Power:
 For 1 footstep current= 10mA
 For 1 footsteps voltage=12V
 1 footstep power=120mWatt
 1 footstep power=10*12

10. Continue….
 Now,
 For 100 footsteps current=1A
 For 100 footsteps voltage=12V
 100 footsteps power=1*12
 100 footsteps power=12Watt

100 1 12 12
500 5 12 60
1000 10 12 120
1500 15 12 180
2000 20 12 240

13. Future Scope
The piezoelectric crystals have being start better use with the
positive result . In Pakistan, maximum public movement is
observed in railway station,airports and shopping malls. Hence
this place can be used for piezoelectric crystals for generation
of electric power. Apart from all the above places attempts are
made to develop energy from our daily life by initialing
piezoelectric in shoes thus in each step piezoelectric crystal can
be compressed which can turned enough power to charge a
cell phone,mp3 player etc through this we can generate
electric power and used that for small electronic gadgets.
