smart screen - design showcase 2014
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.TRANSCRIPT

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 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 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.
