“…There is also a significant linear relationship between the total shadow area and the total load on the legs (Zheng et al., 2016). It provides a method to estimate the vertical forces acting on the legs for tiny water‐walking animals with the least possible error (Ma et al., 2020). Further, it can be utilized to precisely determine the vertical pressures during motion along with changes in the movement of the legs (Lu et al., 2018).…”

Water striders (Gerris argentatus) move across the water surface by taking advantage of the surface tension, which supports their bodyweight without breaking. During locomotion, the midlegs are primarily responsible for generating thrust, whereas the other legs support the body. Although the aspects of standing and locomotion on the water surface are well understood, relatively fewer studies concerned the coordinated biomechanical movements of the legs. In order to maintain buoyancy of the body on the water surface, the leg positions must be adjusted to distribute the bodyweight appropriately. The present study investigates distribution of the bodyweight on the legs in relatively small water striders. We aimed to understand how loading on the legs changes during sculling that leads to sliding of the body on the water surface. The assistance of all legs at every moment enables the body to maintain its floating during standing and striding. Water striders can achieve a gentle striding through the midlegs driving phase in association with smooth load shifting among their legs, which are positioned in a specific configuration to support the insect on the water surface.

“…As the commonly seen structures on many natural organism surfaces, micro-nano filament, pillar, setae, and cilia are slender, hair-like structures that protrude from many types of cells, − providing living organisms with impressive superhydrophobicity, quantified by a water contact angle (CA) larger than 150° and a sliding angle (SA) less than 10°. Based on the well-known wetting mechanism of Cassie–Baxter theory, the more slender and sharp-pointed the surface asperities are, the more superior would be the water repellency obtained, which indicates that filament, setae, pillar, and cilia arrays that have the minimum interfacial contact area with liquid can impart more superior water repellency to the surface compared with other surface morphologies when without considering the influence of material properties.…”

In this study, different flexible structures that are morphologically like the micro-nano pillars, setae, and cilia on many natural organism surfaces are created with a novel fabricating strategy to explore the phenomenon and mechanism of static and dynamic droplets forming on them. Just by adjusting the mold pattern during fabrication, different micro/nanomorphologies including micro–nano pillar, filament, or flake arrays could be conveniently obtained on a pristine smooth film surface. Due to the existence of uniformly distributed hierarchical micro–nano structure arrays that are composed of top-down nanoscale filamentous tips, micro block bases, and grooves on the film, air trapped in arrays connects the atmosphere continuously and forms a successive air-pocket layer, which greatly reduces the solid–liquid interfacial fraction and endows the micro–nanotextured film with the capability of superhydrophobicity, low-adhesion, self-cleaning, anti-icing, and deicing characteristics. Through various mechanical and chemical tests, the film has demonstrated its robustness, making it highly suitable for a wide range of practical engineering applications.

“…In this paper, a novel bionic viscoelastic-polymer micro-force (VPMF) sensor based on the shadow method was proposed to measure micro force and displacement precisely with good linear performance. It was inspired by the phenomenon that the water strider walked on the water surface under sunlight and oval shadows, hundreds of times wider than the diameter of legs, were formed at the bottom of the pond due to the superhydrophobic legs [22]- [28]. The transparent viscoelastic polymer was used as the elastic sensitive element, whose damping property could effectively suppress environmental disturbances, improving the measurement precision [29]- [31].…”
