21. Use of materials in the future
Refer to all new materials and modifications to existing materials
to obtain superior performance in one or more characteristics that
are critical for the application under consideration.
Example
Metal Oxide-based Electrode nanostructures
- high specific capacity/capacitance,
The Boeing 787 Dreamliner utilize nearly half carbon fiber
reinforced plastic for the airframe make it 20% lighter that previously
used aluminum based airframe
Advance Material
22. Use of materials in the future
Smart materials are designed materials that have one or more properties
that can be significantly changed in a controlled fashion by external
stimuli, such as stress, temperature, moisture, pH,
electric or magnetic fields.
Smart – able to sense changes in their environments and then respond
to these changes in predetermined manners
Two components :
1) Piezoelectric
2) Photovoltaic
3) Sensors – detect an input signal such as movement, temperature etc
4) Actuator – performs a responsive & adaptive function
Smart Material
23. Types of smart material
Piezoelectric materials are materials that produce a voltage
when stress is applied
pH-sensitive polymers are materials that change in
volume when the pH of the surrounding medium changes.
Thermoelectric materials are used to build devices
that convert temperature differences into electricity and
vice-versa.
Photomechanical materials change shape under exposure
to light.
