2. INTRODUCTION
a material
responds to a
specific type of
stimulus by
generating a
specific type of
output .
The result
pressure or
motion so the
charge will line
with the surface
and will produce
flow of electric
current
Piezo electric

3. OUTLINE
• Introduction
• Activity 1: evading motion detection
• Activity 2: taking a tour of some sensors
• Activity 3: making a microphone
• Activity 4: exploring the piezo effect
• Activity 5: measuring the piezo effect
• Design Project : coin counter
• Product Idea: modern methods of irrigation
by saving energy

4. ACTIVITY 1
EVADING MOTION DETECTION
• OBJECTIVE :
DISCOVER THE MOTION DETECTOR
• PROCEDURE :
WE PUT THE SENSOR IN SPECIFIC HEIGHT THEN MEASURED HOW
LONG THE MOTION DETECTOR CAN DETECT
• RESULT :
10 FOOTS FROM THE MOTION DETECTOR
• CONCLUSION :
WE REALIZED WHAT THE DETECT SHAPE IS CONE SHAPE & IT
DETECT THE BODY TEMP.

5. ACTIVITY 2
TAKING A TOUR OF SOME
SENSORS
• OBJECTIVE :
DISCOVER HOW THE BIRD SENSOR WORKS.
• PROCEDURE:
WE CLAPPED THEN WE TOUCH THE BIRD
• RESULT :
THE SENSOR WORKED
• CONCLUSION:
THE SENSOR WAS DETECTING THE SOUND OF CLAPPING SO IT
WORKED AFTER IT.

6. ACTIVITY 3
MAKING A MICROPHONE
• OBJECTIVE :
MAKE MICROPHONE BY PVDF FILM
• PROCEDURE:
WE ATTACHED THE TWO TYPES OF PVDF FILM
• RESULT :
TABLE
• CONCLUSION:
1-THE RIGID FILM ABLE US TO HEAR THE SOUND
CLEARLY
2-THE FLEXIBLE ABLE US TO HEAR THE SCRATCH

7. ACTIVITY 4
EXPLORING THE PIEZO EFFECT
• OBJECTIVE :
WE BUILD THE PVDF MONOMER FROM LEGO
• PROCEDURE:
WE BUILD THE PVDF MONOMERS AND JOIN THEM TOGETHER
TO FORM POLYMER
• RESULT :

8. ACTIVITY 5
MEASURING THE PIEZO
EFFECT
• OBJECTIVE :
WE OBSERVE THE EFFECT OF THE BALLS ON THE SENSOR
• PROCEDURE:
WE AFFECT A FORCE ON THE BALL
• RESULT :
THE BIG BALL EFFECT MORE THAN THE SMALL ONE
• CONCLUSION:
AS HEAVIER THE BALL THE EFFECT IS BIGGER

9. DESIGN PROJECT :
DESIGNING COIN COUNTER
• OBJECTIVE :
WE OBSERVE THE WEIGHT OF THE COINS ON THE
SENSOR
• PROCEDURE :
WE AFFECT A FORCE ON THE COINS
• RESULT :
THE BIG COIN EFFECT MORE THAN THE SMALL COIN
• CONCLUSION :
AS HEAVIER THE COIN THE EFFECT IS BIGGER

16. • WE RECOMMEND OUR PROJECT TO BE APPLIED ON
THE PLANTS IN THE STREET PAVEMENTS
IRRIGATION SYSTEMS AND OUR SOLAR PANEL ON
THE STREET LIGHT TO PROVIDE BOTH THE STREET
LIGHTS AND THE STREET PAVEMENTS IRRIGATION
SYSTEM.
• WE RECOMMEND OUR PROJECT TO MINISTRY OF
ENVIRONMENT TO SAVE WATER
• WE RECOMMEND OUR PROJECT TO QATAR GENERAL
