NASA Reports: Japan’s ancient art of paper folding has inspired the design of a
potentially trailblazing “smart” radiator that a NASA technologist is
now developing to remove or retain heat on small satellites.
Vivek Dwivedi, a technologist at NASA’s Goddard Space Flight Center in
Greenbelt, Maryland, has teamed with a couple of researchers at Brigham
Young University in Utah to advance an unconventional radiator that
would fold and unfold, much like the V-groove paper structures created
with origami, the art of transforming a flat piece of paper into a
finished sculpture.
In collaboration with Raymond Adomaitis, a professor at the University
of Maryland in College Park, Dwivedi plans to lower the transition
temperature by applying very thin films of silver and titanium to the
vanadium-oxide using sputtering and a technique called atomic layer
deposition, or ALD. ALD is performed in a state-of-the-art reactor
developed by both Dwivedi and Adomaitis. With ALD, engineers literally
can apply atomic-sized layers of different materials onto intricately
shaped structures — much like how a cook layers different ingredients to
make a pan of lasagna.
