In minimally invasive surgery, the tendency for human tissue to adhere electrosurgical scalpel can complicate procedures and elevate risk of medical accidents. Consequently, development an with anti-sticking coating is critically important. Drawing inspiration from nature, we identified that leaves Setaria Virids exhibit exceptional non-stick properties. Utilizing this natural surface texture as a model, designed fabricated specialized scalpels. Employing nanosecond laser direct writing ablation technology, created micro-nano textured on high-frequency mimics structure found leaves. Subsequently, TiO2 was deposited onto ablated via magnetron sputtering, followed by plasma-induced hydrophobic modification treatment octadecyltrichlorosilane (OTS) enhance surface’s affinity silicone oil, thereby constructing self-lubricating surface. The spreading behavior deionized water, absolute ethanol, dimethyl oil investigated confirm effectiveness self-lubrication mechanism. Furthermore, sticking force quality are compared between standard demonstrate efficacy laser-ablated in preventing sticking. findings indicate using exhibits superior

Due to its scientific significance and practical applications, the common natural phenomena of drops impacting on inclined surfaces have attracted extensive attention. Previous research has primarily reported distinct morphology dynamic behavior superhydrophobic compared impact horizontal scenarios. One distinguished feature drop impingement is asymmetric shapes drop, which accounts for different underlying physics impacts surfaces. However, forces exerted by surface during remained unknown. In this study, we present a direct measurement normal force using high-precision sensor. We observe temporal evolution identify two peak occurring spreading retraction stages, respectively. Our findings lie investigating variation these with Weber number, based scaling arguments. reveal that asymmetrical must be taken into account especially in scenarios large velocities tilt angles revise theoretical model second force. The work sheds new light drops.

Wedge-shaped superhydrophilic tracks have been considered as one of the most effective ways to transport droplets for diverse cutting-edge applications, e.g., energy harvesting and lab-on-a-chip devices. Although significant progress, such serial wedge-shaped with curved edges, has evolved advance liquid transport, ultrafast long-distance transporting drop-shaped remains challenging. Here, inspired by cactus spine that enables fast droplet spindle knot spider silk, which is capable collecting condensate from a wide range distances, we created patterns optimized their side edges convex brachistochrone curve boost acceleration. The junctions were meanwhile reformed into concave curves lower barrier sustained transport. For in drop shapes long distance at high velocity, slenderized greatest extent suppress spreading thus prevent degradation Laplace driving force. Moreover, junction determines striding was carefully designed based on principle minimizing momentum loss. exquisite architecture design pushed maximum instantaneous velocity 207.7 mm·s–1 an outermost 120.5 mm, exceeding wettability or geometric gradient reports. transported volume can be readily regulated simply scaling architectures. enhanced facilitates motion departure cohered droplets, enabling 1.9-fold rise water collection rate 12-fold increase heat transfer coefficient during fog harvest test. This scalable, controllable, easily fabricatable surface provides essential pathway realizing high-performance manipulation possibly pioneers substantial innovative applications multidisciplinary fields. Those include but are not limited harvesting, devices, MEMS systems.

Wearable sensors have attracted considerable interest due to their ability detect a variety of information generated by human physiological activities through physical and chemical means. The performance wearable is limited stability, endowing with superhydrophobicity one the means enable them maintain excellent in harsh environments. This review emphasizes imperative progress flexible superhydrophobic for devices. Besides, wettability principle mechanism are briefly introduced propose combination sensors. Next, substrates sensors, including but not to, polydimethylsiloxane, polyurethane, gel, rubber, fabric, described depth, also respective fabrication processes performances. Moreover, utility normal intelligent environment described, highlighting application monitoring signals, such as movement, pulse, vibration, temperature, perspiration, respiration, so on. Finally, this evaluates challenges dilemmas that must be overcome further development improve functional paving way expansion into advanced sensing systems.
