Special Issue Information

Dear Colleagues,

Learning from nature is always worthwhile, especially in relation to understanding its strategies of fabrication and manufacturing. Inspired by biology, researchers have proposed a great number of structural materials demonstrating a high performance, but their methods of preparation may not be as smart or effective as natural ones. Thus, the aim of this Special Issue is to collect contributions from different laboratories working on biomimetic fabrication and manufacturing. By covering issues ranging from structural materials and metamaterials to photonic crystals, separation membranes, sensors, and smart polymers, this Special Issue offers an updated view of the status quo and perspectives in a rapidly developing area of technology and application research. The present collection of papers, taking advantage of the open access format, is expected to provide a paradigm of the power of biomimetic approaches for discovering new and important research avenues, as well as innovative solutions in materials and manufacturing.

To further its aims of combining basic research and applications, this Special Issue is divided into two main parts as follows:

  • Part a) Materials—covering topics such as bioinspired materials; biomimetic structures; biomimetic manufacturing; mechanical biomimetics; molecular biomimetics; functional biomimetics; smart materials; and hierarchical structure design.
  • Part b) Applications—including optical measuring; gas analysis; electric sensors; acoustic devices; microrobots; wearable devices; and medical supplies.

We believe that this initiative will bridge an important gap in biomimetic fabrication and manufacturing, as well as stimulating the enthusiastic contributions of leading experts within this field.

The development of alginate/polyacrylamide hydrogels for various biomedical applications has attracted significant interest, particularly due to their potential use in wound healing and tissue engineering. This study explores the fabrication of these hydrogels via 3D bioprinting with ultraviolet light curing, focusing on how the alginate concentration and curing speed impact their mechanical properties. Rheological testing was employed to examine the viscoelastic behavior of alginate/polyacrylamide hydrogels manufactured using a 3D bioprinting technique. The relaxation behavior and dynamic response of these hydrogels were analyzed under torsional stress, with relaxation curves fitted using a two-term Prony series. Fourier Transform Infrared (FTIR) spectroscopy was also employed to assess biocompatibility and the conversion of acrylamide. This study successfully demonstrated the printability of alginate/polyacrylamide hydrogels with varying alginate contents. The rheological results indicated that 3D bioprinted hydrogels exhibited significantly high stiffness, viscoelasticity, and long relaxation times. The curing speed had a minimal impact on these properties. Additionally, the FTIR analysis confirmed the complete conversion of polyacrylamide, ensuring no harmful effects in biological applications. The study concludes that 3D bioprinting significantly enhances the mechanical properties of alginate/polyacrylamide hydrogels, with the alginate concentration playing a key role in the shear modulus. These hydrogels show promising potential for biocompatible applications such as wound healing dressings. Full article

The rapid advancement of artificial intelligence continuously increases the demand for high computing power, leading to substantial rises in chip power consumption and heat generation. As a result, efficient thermal management has become essential. Inspired by the placoid scales on shark skin, we designed a bionic microchannel heat sink by introducing biomimetic structures on the inner channel surfaces to enhance heat dissipation. Numerical simulations are performed to investigate thermal behavior under different structural configurations. The results show that the arrangement, number, and inclination angle of the placoid structures significantly influence heat transfer by modifying flow patterns, enlarging the heat transfer area, and altering the thermal boundary layer. Notably, at a flow velocity of 2 m/s, the cooling performance differs significantly between inclination angles of 0° and 17°. Moreover, the influence of different quantities of placoid structures shows a consistent trend across various flow rates. These findings demonstrate that bionic surface structures can effectively improve the thermal performance of microchannel heat sinks, offering a promising strategy for high-performance chip cooling.
