Auxetic Origami Surface [AOS-1]

For this project, we developed a responsive surface based on
the behaviors exhibited by the oxalis plant that we had
studied earlier: the ability to change shape in response to
light levels; clustering to reduce the number of actuators;
and the repetition of a single auxetic form that could expand
or contract to minimize or maximize exposure to light.
Pelican Pouch

"The pink-backed pelican uses its distendable throat pouch as a fishing net, scooping fish and crustaceans from the water as it swims. When it opens its bill underwater, the sudden inflow of water carries the prey in with it. Then the pelican raises its head to drain out the water before swallowing the prey." (Foy and Oxford Scientific Films 1982:157)
The Pelican's pouch shows the potential of flexible/expanding membranes at the interface of wet/dry environments.
