Rectified Motion of Liquid Drops on Gradient Surfaces Induced by Vibration

When a liquid drop (1−2 μL) is placed on a surface possessing a continuous gradient of wettability, it moves toward the more wettable part of the gradient with typical speeds of 1−2 mm/s. This low speed arises because the driving force due to surface tension is reduced by contact angle hysteresis. T...
