Nastic Actuation: Electroosmotic Pumping for Shape-Changing Materials
Final rept. 1 Mar 2009-30 Nov 2011
MARYLAND UNIV COLLEGE PARK OFFICE OF RESEARCH ADMINISTRATION AND ADVANCEMENT
Pagination or Media Count:
The goal was to demonstrate a flexible actuation technology that would enable smart materials with both large stresses and strains. Using microchannels that would pump fluid by electroosmosis to deform flexible materials, we experimentally demonstrated devices that created large material deformations at high pressure, and whose performance matched theoretical predictions.
