DESCRIPTION

With the muscle wire in its relaxed state the screen remains closed, however, once heat is applied the smart screen unpuzzles, allowing it to function as a double skin façade system. This can be controlled by engineering the wire to respond to very specific temperatures. In this experiment, the smart wire contracts when reaching a temperature of 70ºF, accomplished by inducing electrical current through the nickel titanium muscle wire, divided in 3x 24cm long pieces, two connected in parallel on both sides of the screen, and one on top, serving as the muscles that open the screen. A set of 4 compression springs were used to return the screen back to a closed position.

    Concept summary With the muscle wire in its relaxed state the screen remains closed, how-

    ever, once heat is applied the smart screen unpuzzles, allowing it to function

    as a double skin faade system. This can be controlled by engineering the

    wire to respond to very specific temperatures. In this experiment, the smart

    wire contracts when reaching a temperature of 70F, accomplished by induc-

    ing electrical current through the nickel titanium muscle wire, divided in 3x

    24cm long pieces, two connected in parallel on both sides of the screen, and

    one on top, serving as the muscles that open the screen. A set of 4 compres-

    sion springs were used to return the screen back to a closed position.
