SMART Materials: Top Trump Cards
YOUR TASK is to produce a set of 5 cards, one for each SMART material.
Each card should show the following
• Properties• Examples of use• Reasons for use• Improvements on
traditional materials
SMART Materials:Shape Memory alloy
Properties:Bendable, it will return to its original shape if heated above a certain temperature Examples of use: Sprinklers in fire alarm systems, spectacle frames, coffee machines.
Reasons for Use: It’s easily shapen and keeps its shape
Improvements on traditional materials:Glasses had to be re-bended by hand but now you can use heat

SMART Materials:Shape Memory
polymer
Properties: Will return to its original shape if heated above a certain temperature. A good insulator.Examples of use: Window sealing foam, sensors and robots
Reasons for use: Strong, low cost, can be triggered by temperature and light
Improvements on traditional materials: Can be tailored to a broad range of materials and temperatures.

SMART Materials:Piezoelectric actuators
Properties: When electricity is applied to a Piezo Actuator it changes shape by an small but amount. They can be “stacked”Examples of use: Controlling hydraulic valves, adjusting machining tools and some motors Reasons for Use: Very small and precise movements, no motors or gears to go wrong.
Improvements on traditional materials: Easy to control pumps and valves. Very small & controlled movement unlike motors

SMART Materials:Piezoelectric transducers
Properties: When under impact they create a small electrical current. When electricity is applied they move a small amount.Examples of use: Guitar hero drum sensors. Touch sensitive surfaces, engine sensors
Reasons for Use: Reliable and sensitive way of creating an electrical signal from movement or vice versa.Improvements on traditional materials: Small movement needed unlike switches. Simpler than a motor for small movements

SMART Materials:Electrochromic
materials
Properties:Change colour when electricity is applied
Examples of use: Smart windows, electrochromic mirrors and electrochromic display devices
Reasons for Use: Privacy in office windows, automatic tiniting of windows depending on sunImprovements on traditional materials: Usually you have to choose the colour of a material and it can’t be changed easily

And Wikipedia of course but keep it simple.
Youtube if you must but DO THE WORK not just waste time gazing at videos!
Good Luck
