Richard Meritt. Just as a chameleon changes its color to blend in with its environment, Duke University engineers have demonstrated for the first time, that they can alter the texture of plastics on demand; for example, switching back and forth between a rough surface and a smooth one.
By applying specific voltages, the team has also shown that it can achieve this control over large and curved surface areas.
Keep on lecturing.
