Cross-discipline technological advancements are on the rise. The integration of art, science and the environment is inspiring the creation of products that are both efficient and planet-friendly. A recent collaboration involves art students and scientists from the University of Michigan at Ann Arbor (livescience.com). Using the ancient Japanese paper cutting art of Kirigami, the team developed a lightweight sun-tracking solar cell that has the potential to increase energy generation through extended periods of solar absorption. The key is the lightweight polyimide film used in the design. It’s both flexible, and lightweight and its Kirigami cuts allow a “bending motion” for efficient sun-tracking.
