“…Hydrogels are common polymer materials that can contain a large amount of water inside due to their 3D polymer network. 68,69 Compared to other materials, the hydrogel is generally composed of hydrophilic polymer networks and its interior is lled with loose pores, which provide a pathway for water transportation. 15,[70][71][72] When conditioning the polymer network of a hydrogel, the highly hydratable polymeric network can weaken the force of water molecules, so the evaporation rate is greatly increased by using this principle.…”

The healing of diabetic wounds is hindered by various factors, including bacterial infection, macrophage dysfunction, excess proinflammatory cytokines, high levels of reactive oxygen species, and sustained hypoxia. These factors collectively impede cellular behaviors and the healing process. Consequently, this review presents intelligent hydrogels equipped with multifunctional capacities, which enable them to dynamically respond to the microenvironment and accelerate wound healing in various ways, including stimuli ‐responsiveness, injectable self‐healing, shape ‐memory, and conductive and real‐time monitoring properties. The relationship between the multiple functions and wound healing is also discussed. Based on the microenvironment of diabetic wounds, antibacterial, anti‐inflammatory, immunomodulatory, antioxidant, and pro‐angiogenic strategies are combined with multifunctional hydrogels. The application of multifunctional hydrogels in the repair of diabetic wounds is systematically discussed, aiming to provide guidelines for fabricating hydrogels for diabetic wound healing and exploring the role of intelligent hydrogels in the therapeutic processes.

“…Nature provides a wealth of inspiration for scientists studying the remarkable properties of biological surfaces. − The principles behind these biological surfaces have led to novel concepts and ideas for surface texture design. , For instance, the polygonal-shaped textures found on snakeskin reduce friction between the skin and the surroundings during rubbing locomotion . Inspired by this, polygon surface textures are often fabricated on thrust rings to enhance frictional properties .…”

Magnetic fluid shock absorbers (MFSAs) have been successfully utilized to eliminate microvibrations of flexible spacecraft structures. The method of enhancing the damping efficiency of MFSAs has always been a critical issue. To address this, we drew inspiration from the tree frog’s toe pads, which exhibit strong friction due to their unique surface structure. Using 3D printing, we integrated bionic textures copied from tree frog’s toe pad surfaces onto MFSAs, which is the first time to combine bionic design and MFSAs. Additionally, this is also the first time that surface textures have been applied to MFSAs. However, we also had to consider practical engineering applications and manufacturing convenience, so we modified the shape of bionic textures. To do so, we used an edge extraction algorithm for image processing and obtained recognition results. After thorough consideration, we chose hexagon as the shape of surface textures instead of bionic textures. For theoretical analysis, a magnetic field–flow field coupling dynamic model for MFSAs was built for the first time to simulate the magnetic fluid (MF) flow in one oscillation cycle. Using this model, the flow rate contours of the MF were obtained. It was observed that textures cause vortexes to form in the MF layer, which produced an additional velocity field. This increased the shear rate, ultimately leading to an increase in flow resistance. Finally, we conducted vibration reduction experiments and estimated damping characteristics of the proposed MFSAs to prove the effectiveness of both bionic texture and hexagon surface textures. Fortunately, we concluded that hexagon surface textures not only improve the damping efficiency of MFSAs but also require less MF mass.
