Flexible strain sensors are being increasingly applied as wearable electronic materials owing to their functional characteristics (e.g., light weight, stretchability, wearability), which highlight their enormous potential in health monitoring and medical care. However, challenges related to signal distortion and corrosion risks arise when they are used under extreme or harsh conditions. Superhydrophobic flexible strain sensors combine the water‐repellent, anticorrosion, and anti‐fouling features of the superhydrophobic coating with the high ductility and high sensitivity of the flexible strain sensor, thereby broadening the application scope of strain sensors, especially for underwater wearable sensing. However, the underwater sensing applications of superhydrophobic flexible strain sensors have not yet been thoroughly summarized. This review presents the key performance parameters and design strategies of superhydrophobic flexible strain sensors, with an emphasis on the diverse applications for underwater sensing.

“…After chemical oxidation, the surface of the step-like macro groove array was uniformly covered with micro particles and nano needles (figure 9(i)), and with subsequent fluorination and injection with silicone oil, slippery surfaces with step-like macro groove arrays were obtained under different spinning speeds (figures 9(j)-(l)). Compared to ultrafast lasers, nanosecond lasers have lower costs, higher efficiencies, and reduced environmental condition requirements [170][171][172][173][174], making nanosecond laser etching technology suitable for the industrial production of bio-inspired materials with MAAs. Pan et al [88] used nanosecond laser etching technology to fabricate macro-conical pillar arrays (figure 10(a)), and figures 10(b) and (c) shows the SEM images of the fabricated macro-conical pillar arrays.…”

Bio-inspired macrostructure array (MAA, size: submillimeter to millimeter scale) materials with special wettability (MAAMs-SW) have attracted considerable attention due to their outstanding performance in many fields, such as oil repellency, liquid/droplet manipulation, anti-icing, heat transfer, water collection, and oil−water separation. In this review, we mainly focus on recent developments in the theory, design, fabrication, and application of bio-inspired MAAMs-SW. First, we briefly introduce the basic theory of special wettability. Afterwards, we discuss representative structures and corresponding functions of some biological surfaces. Then, we summarize fabrication methods of special wetting MAAs from the three categories of additive manufacturing, subtractive manufacturing, and formative manufacturing, including 3D printing, laser etching, wire electrical discharge machining, micro-mechanical cutting machining, electrochemical machining, template method, and imprinting method. In addition, we demonstrate the applications of these MAAMs-SW. Lastly, the challenges and directions of future research on bio-inspired MAAMs-SW are briefly addressed.

“…In general, superhydrophobic surfaces can be obtained by building rough structures on low surface energy materials or by reducing the surface energy of existing rough structures. − Chemical etching and electrodeposition are utilized to fabricate a superhydrophobic surface on H62 brass . It is observed that etching significantly influences the surface morphology and SWCA of the H62 brass.…”
