Special Issue Information

Dear Colleagues,

Many species have evolved various attachment systems. Strong, controllable, and repeatable adhesion in species adapted to various environments is a key factor in survival, as it makes activities such as climbing, attaching, and catching more efficient. Adhesion between solid bodies depends on various forces, such as van der Waals forces, capillary forces, electrostatic attraction, and suction. Current research indicates that the mechanism behind geckos’ strong adhesion abilities depends not only on van der Waals forces from the fibrillar dimension and structure but also on capillary effects from humidity and electrical charges from gecko-specific setal beta-properties. In addition, the adhesion mechanisms of other species such as beetles, spiders, frogs, octopuses, and mussels are investigated. Inspired by the functions of the above-mentioned biological adhesion, bioinspired adhesives have been rapidly developing for academic and industrial applications, and various functional devices such as grippers, robots, and wearable sensors have been created. It has been demonstrated that bioinspired adhesives have important potential application value in various fields such as robotics, aerospace, and medical devices.

This Special Issue will focus on innovative research and industry developments in bioinspired adhesives, and we especially encourage submissions on the adhesion mechanisms of various species, the design and preparation of smart adhesives, and the application of biomimetic adhesives in various environments, such as space, underwater, and the human body. The goal of this Special Issue is to promote scientific development in this field and provide a platform for the exchange of new theories, concepts, and technologies in bioinspired adhesives.

In contrast to traditional hydrogels, which are susceptible to water evaporation and structural degradation, non-hydrogel materials are engineered for superior stability and consistent performance. Here, we report an innovative piezoelectric polyvinyl chloride/multi-walled carbon nanotube polymer gel (PVC/MWCNT polymer gel, PMPG) with exceptional linearity (as low as 1.31%), high sensitivity (50–310.17 mV), rapid response (172–189 ms), and thermal stability. Under strain induction, ordered rearrangement of dipoles in PMPG and the enhancement of MWCNTs generate a potential difference. Increasing MWCNT content enhances output voltage, sensitivity, conductivity, maximum stress, Young’s modulus, and toughness, while reducing nonlinear error. Higher dibutyl adipate (DBA) content increases output voltage and slightly improves sensitivity but decreases mechanical strength. The optimal PMPG (PVC:DBA = 1:5, 1 wt% MWCNTs) exhibited outstanding performance. It exhibits a nonlinear error as low as 1.31%, a conductivity of 25.4 μS/cm, an 80% compressive strain tolerance (273 kPa stress), and dimensional stability for 90 days in air. By integrating PMPG with machine learning algorithms, soft robotic grippers gain advanced contact perception capabilities, enabling applications in medicine, rescue, exploration, and other fields requiring fine manipulation and adaptability. This work highlights PMPG’s potential as a stable, high-performance material for soft robotics and beyond. Full article
