Abstract: Adaptive surface wrinkles are demonstrated to exhibit a peristaltic motion and a size-selective transportation of micro-objects under thermal stimulus. The bilayered materials made of thermoresponsive poly(N-iso-propylacrylamide) and hybrid silica form responsive wrinkles of submillimeter dimensions with temperature variation. This hydrogel-based actuation works in a near-physiological environment, which meets the critical requirement for artificial alternatives in bioapplications.
