SCIENCE.

2. Why we choose this topic ?
Because, in our daily life we use so many smart materials
but we don’t know their function.
If we know their functioning we can improve technology
and our knowledge.
Smart materials are the materials which have certain
characteristics by which they have special position in our
life.

3. INTRODUCTION:
Smart materials are new generation materials surpassing
the conventional and functional materials .
which posses the ability to change their physical property
in the specific manner in response to specific stimulus.
 The stimuli could be pressure, temperature, electrical and
magnetic fields, chemical, hydrostatic pressure or nuclear
radiation.
 The associated changeable physical property could be
shape stiffness, viscosity or damping.
 Smartness describes self-adaptability, self-sensing, memory
and multiple functionalities of the materials or structures.

4. APPLICATIONS:
as per as the technical applications of smart materials is
concerned, it involves composite material embedded with these
applications.
Fiber optics
Actuator
Sensor
Micro electro mechanical systems
Vibration control
Sound control, shop control
Food safety
Automatic doors

5. AUTOMATIC DOORS:
 When we step on the mat the
sensors send a signal to the
automatic doors operate doors
operate an optic or motion sensor
sense motion nearby, they trigger
the automatic doors to open and
then close.

6. USES:
• Automatic doors have many
useful purposes which is why
you can find them in many
different types of locations .
from supermarket to airport
and many types of large
buildings.
• Easier for people to get into
and out of buildings . They are
especially helpful for people
who are handicapped.

7. FOOD
SAFETY:
Active food contact
materials absorb or
release substances in
order to improve the
quality of packaged
food or to extend its
shelf life.

8. AWARENESS:
Specify for industry which
aspects EFSA takes into
account when accessing
the safety of these
substances and the types
of data needed to conduct
the assessments.
The evaluations also
consider the possible
influence of manufacturing
process and intended uses
of specific substance.

9. CONCLUSION:
• Today, the most promising technologies for lifetime
efficiency and improved reliability include the use of smart
materials and structures.
• Controlling the composition and microstructure of any new
materials are the ultimate objectives of research in this field.
• And is crucial to the production of good materials.
