Miniature soft robots are mobile devices, which are made of smart materials that can be
actuated by external stimuli to realize their desired functionalities. Here, the key …

The interest in superhydrophobic surfaces has grown exponentially over recent decades.
Since the lotus leaf dual hierarchical structure was discovered, researchers have …

Walking on water is a unique locomotion mode found in aquatic living creatures. However, it
remains challenging to create light-driven aquatic soft robots that can walk freely on water …

Mimicking living creatures, soft robots exhibit incomparable adaptability and various
attractive new features. However, untethered insect-scale soft robots are often plagued with …

Aquatic locomotion is challenging for land-dwelling creatures because of the high degree of
fluidity with which the water yields to loads. We surprisingly found that the Chinese rice …

Active matter systems feature a series of unique behaviors, including the emergence of
collective self-assembly structures and collective migration. However, realizing collective …

Jum** on water is a unique locomotion mode found in semi-aquatic arthropods, such as
water striders. To reproduce this feat in a surface tension–dominant jum** robot, we …

Computational methods have been extended recently to allow for the presence of moving
contact lines in simulated two-phase flows. The predictive capability offered by these …

Miniaturized rotors based on Marangoni effect have attracted great attentions due to their
promising applications in propulsion and power generation. Despite intensive studies, the …

Although negligible at macroscopic scales, capillary forces become dominant as the sub-
millimetric scales of micro-electro-mechanical systems (MEMS) are considered. We review …
