Artificial bionic skin material is playing an increasingly important role in the field of medicine and bionic engineering and becoming a research hotspot in many disciplines in recent years. In this work, the digital moiré method was used to measure the mechanical field of the bionic skin material under different suturing conditions. Through the digital image process, the deformation characteristics and the stress distribution near the contact area between the bionic skin material and the suture were obtained and discussed. The different healing effects caused by suturing mode were further explored, which can provide mechanical guidance for wound suturing in clinical medicine.

Achieving UVA/B-selective, skin-inspired nociceptors with perception and blockade functions at the single-unit device level remains challenging. This is because the device necessitates distinct components for every performance metric, thereby leading to complex preparation processes and restricted performance, as well as the absence of deep UV (UVB and below)-selective semiconductors. Here, to address this, we develop a structure-simplification skin-inspired nociceptor using a reverse type-II CuAgSbI/MoS heterostructure.

During the long course of evolution, fish have developed complex skin structures to adapt to the dynamic aquatic environment. These skin features not only reflect optimal adaptation to the aquatic environment but also play a key role in effectively reducing fluid drag and improving swimming efficiency, to reveal the intrinsic connection between the complex skin structure of fish and drag reduction performance and to provide new design ideas for the drag reduction surface of underwater vehicles. Based on the different drag reduction characteristics of fish skin structures, this paper divides existing biomimetic drag reduction technologies into three categories: riblet drag reduction, flexible drag reduction, and composite drag reduction.

Idiopathic Parkinson's disease (iPD) is the second most common neurodegenerative disease after Alzheimer's disease (AD). Mutations in the SCNA gene, which encodes the protein alpha synuclein (α-syn), are associated with familial forms of Parkinson's disease (PD). Additionally, Lewy bodies (LBs) rich in α-synuclein are a hallmark of idiopathic Parkinson's disease (iPD) pathology.

Flexible superhydrophobic materials are attractive in separation technology, thermal management, anti-icing, and wearable electronics since their adaptability to curved surfaces and deformation. However, their fragility and high susceptibility to abrasion, caused by the destruction of micro/nano structures, remain significant challenges. A skin-inspired gradient design is proposed to combine flexibility and superhydrophobicity by facilitating the nanoparticle engulfment in polymer through pressure, electrostatic forces, and enhanced capillary forces.

The clinical treatment of infected skin injuries caused by exogenous bacteria presents significant challenges, and traditional therapies struggle to achieve multiple therapeutic effects simultaneously. Herein, a mussel-inspired photothermal antibacterial self-repairing hydrogel (BA-PDZn-N) was designed for accelerating infected wound healing. Multi-network structures were constructed through free radical polymerization and dynamic borate bonding between acrylamide, 3-acrylamidophenylboronic acid, and polydopamine (PDA), as well as metal ligand chelation between PDA and Zn for uniform porosity.
