Magnificent!
Can you post a video of that process?

Thanks :) The assignment was to create a screen prototype that opens and closes by reacting to changes in temperature. This is achieved by using a shape memory alloy wire (commonly known as muscle wire) which acts as both sensor, motor and actuator by applying a specific amount of voltage (15.82v in this case) which brings the wire temperature to 70 degrees. Once the wire cools down it goes back to a relaxed state, allowing the screen to go back to a closed position.

Looks interesting.
What is this?
