Smart art today for smart building ventilation tomorrow
from Earth Techling
The "Bloom" installation by University of Southern California architect professor Doris Kim Sung is composed of 14,000 pieces of thermobimetal, a smart material that changes its shape when hit by the heat of the sun. "Bloom" was constructed with two thin sheets of these metals, each with different expansion rates, which were then laminated together. Because one sheet expands faster than the other, when the temperature rises, the metal sheets curl up. When the mercury dips again, these sheets flatten out.
