Inspired by geckos» sticky feet, scientists are developing adhesive tapes — by rooting columns of nanotubes in
flexible polymer pieces — that stick many times better than a gecko's foot.
Although the use of rigid metal and plastic parts tends to result in stiff, mechanical motion, a team at the Massachusetts Institute of Technology (M.I.T.) is experimenting with the use of a single
piece of
flexible silicon and urethane
polymer to create robotic fish that smoothly wriggle through the water much like their natural counterparts.
