Researchers develop coating that "twitches" to shake fouling material off ship hulls

http://www.gizmag.com/twitch-antifouling-coating/26063/     /  dynamic change of surface area topology of elastomers is used as a general, environmentally friendly approach for effectively detaching micro- and macro-fouling organisms adhered on the elastomer surfaces. Deformation of elastomer surfaces under electrical or pneumatic actuation can debond various biofilms and barnacles. The bio-inspired dynamic surfaces can be fabricated over large areas through simple and practical processes. This new mechanism is complementary with existing materials and methods for biofouling control /
