Smart materials

Which of the following is not a smart material?

• CFRP

• SMA

• Pizo Electric materials

• Thermo chromic paints

A smart material is

• a material that has a Phd.

• a material that changes its properties during the manufacturing process.

• a material that changes a property in response to an environmental trigger.

Identify the trigger and effect associated with piezoelectric materials

• Trigger = force Effect = Electric charge

• Trigger = UV light Effect = Electric charge

• Trigger = force Effect = change in colour

• Trigger = dark light Effect = can't be see

When discussing smart materials what does SMA stand for?

• Students materials assignment

• Smart metal alloy

• Shape memory metal

• Shape memory alloy

Identify the trigger and effect associated with thermocromic materials

• Trigger = Force Effect = change in colour

• Trigger = temperature Effect = change in colour

• Trigger = temperature Effect = change in shape

• Trigger = force Effect = change in shape

A typical application for a SMA would be

• Ice cream scoop

• Bath plug

• Coffee mug

• Glasses frame

A typical application for an electrical luminescent material would be

• marking of emergency exit path

• Glasses frame

• Coffee cup

• Braces

A typical application for a shape memory polymer would be

• glasses frames

• hacksaw blade

• to join two pipes together

• coffee cup

The trigger and effect associated with a shape memory polymer would be

• Trigger = heat Effect = change in shape

• Trigger = Moisture Effect = electric charge

• Trigger = force Effect = change in colour

• Trigger = pressure Effect = change in colour

An example of a shape memory alloy would be

• Nickel titanium alloy

• Aluminium alloy

• Brass

• Nylon alloy
