“…Then, Gwon et al improved the adhesion performance of the adhesive surface of the inclined structure prepared by 3D printing through an impregnation process (as shown in Figure 9 c). The maximum adhesion force of the adhesive surface with the added silica gel coating was increased by a factor of 4 compared to the unadded one [ 74 ]. However, the adhesion force was still minimal, only 1.53 Kpa.…”

The gecko can achieve flexible climbing on various vertical walls and even ceilings, which is closely related to its unique foot adhesion system. In the past two decades, the mechanism of the gecko adhesion system has been studied in-depth, and a verity of gecko-inspired adhesives have been proposed. In addition to its strong adhesion, its easy detachment is also the key to achieving efficient climbing locomotion for geckos. A similar controllable adhesion characteristic is also key to the research into artificial gecko-inspired adhesives. In this paper, the structures, fabrication methods, and applications of gecko-inspired controllable adhesives are summarized for future reference in adhesive development. Firstly, the controllable adhesion mechanism of geckos is introduced. Then, the control mechanism, adhesion performance, and preparation methods of gecko-inspired controllable adhesives are described. Subsequently, various successful applications of gecko-inspired controllable adhesives are presented. Finally, future challenges and opportunities to develop gecko-inspired controllable adhesive are presented.

“…However, vacuum suction can cause objects to be pressed out of their shape or damaged. [18] In addition, an electrostatic chuck requires a high voltage to operate and is susceptible to damage in electronic devices. [18,19] To overcome this challenge, many researchers have developed soft gripper systems with various dry adhesives inspired by nature, such as geckos [20][21][22][23][24][25] and aphids.…”

“…[20][21][22][23][24][25] Subsequently, elastomers (e.g., Ecoflex silicone elastomer and polydimethylsiloxane (PDMS)) are poured into the mold and cured, resulting in the formation of fibrillar structures. [18,[22][23][24] Although gecko-inspired adhesives fabricated using the above methods exhibit high adhesion strengths, these fabrication processes are relatively complex to handle, require clean environments, and require additional tasks to remove residues. Moreover, many materials used in semiconductor manufacturing, such as photoresists, development solutions, and etchant solutions, are required in the fabrication process.…”

Herein, we report a thermo‐actuated aphid‐inspired dry adhesive that offers tunable and reversible adhesion. It is easily fabricated through three‐dimensional printing using a polylactic acid filament and silicone elastomer, avoiding the use of unfavorable methods for micro‐ and nano‐fabrication and unwanted particles for actuation. The tunable adhesive system mimics aphid biology to achieve adhesion switchability. Switching between adhesion states is enabled by the thermo‐actuated polylactic acid, which has shape memory properties. Additionally, silicone elastomer enables adherence to flat substrates such as glass, silicon wafers, and acryl. The detachment time of the thermo‐actuated aphid‐inspired dry adhesive can be controlled by changing the printing layer height, which is a three‐dimensional‐printing parameter that results in a short detachment time when the printing layer height is small. The adhesion strength was measured by applying different preloads and varying the size of the adhesive area. We also demonstrated the reversibility between the adhesion‐on and adhesion‐off states, revealing good repeatability with similar adhesion strengths. The thermo‐actuated aphid‐inspired dry adhesive has potential applications in transferring silicon wafers. In addition, it can be printed to fit a flat plate of any shape, enabling it to grip the plate stably.This article is protected by copyright. All rights reserved
