Softened double-layer octopus-like adhesive with high adaptability for enhanced dynamic dry and wet adhesion

A Reversible, Versatile Skin‐Attached Haptic Interface Platform with Bioinspired Interconnection Architectures Capable of Resisting Sweat and Vibration

“…The soft FSIA patch was obtained by simple microcontact printing of a soft gel (MED-6342, NuSil, Pennsylvania, USA). [21] The thickness of the soft gel precursor was controlled by centrifugation at 500 rpm for 10 s and 4000 rpm for 50 s on a silicon wafer substrate. The sample was stamped onto a Teflon substrate and cured at 135 °C for 45 min.…”

Review of biomimetic ordered microstructures in advancing synergistic integration of adhesion and microfluidics

“…These range from highly precise and comprehensive instruments that offer intricate and precise analysis to simple daily wearable electronic watches that only provide limited measurements. [1][2][3] However, the limitations of inaccurate and inadequate electronic testing devices require users to seek professional testing, resulting in a signicant investment of time and energy. This is contrary to the current objective of immediate and expert health assessment.…”

Triple-Bioinspired Shape Memory Microcavities with Strong and Switchable Adhesion

“…16,17 However, most reported octopus-inspired adhesives are based on flexible materials, such as polydimethylsiloxane (PDMS), which typically exhibits high elastic recovery properties that hinder the formation and maintenance of conformal contact with rough surfaces, thereby weakening the adhesion strength. 21,22 Furthermore, octopusinspired surfaces often lack the high rough structure required to repel droplets, leading to permanent high liquid adhesion due to the high mobility of the liquids, which can be easily drawn into the cavity. 23 Fortunately, various other life forms in nature can provide inspiration for adhesive surfaces.…”

“…Nature serves as a valuable source of inspiration for developing adhesion structures with strong adhesion, such as geckos, octopuses, , tree frogs, insects, and creepers . For instance, octopuses have numerous suckers on their arms, and a pressure differential between the sucker chamber and the surrounding medium can be formed under the action of muscle movements; thus, a high adhesion toward target substrates can be achieved. , However, most reported octopus-inspired adhesives are based on flexible materials, such as polydimethylsiloxane (PDMS), which typically exhibits high elastic recovery properties that hinder the formation and maintenance of conformal contact with rough surfaces, thereby weakening the adhesion strength. , Furthermore, octopus-inspired surfaces often lack the high rough structure required to repel droplets, leading to permanent high liquid adhesion due to the high mobility of the liquids, which can be easily drawn into the cavity .
