“…This research explores the design of various structures, including triply periodic minimal surfaces (TPMS) with varying thicknesses and volume fractions, providing valuable insights into the geometric intricacies of these structures. However, while the study advances understanding of the thermal and flow behavior of these structures, it may not fully address the complexities involved in modeling the interactions between different unit cell types, especially when these interactions significantly impact the overall structural integrity and functionality [49].…”

“…In addition to auxetic behaviour, there are many other artificial mechanical behaviours like negative stiffness, negative compressibility, and ultra-lightweight ultra-high stiffness properties that are achievable through different types of mechanical metamaterials [10,13]. Such properties are controllable by tuning the unit-cell geometry through several methods like computer-aided design (CAD) and topology optimisation [12,14,15] Due to this unique behaviour, auxetics have been considered for different applications such as prosthetics [16], tissue engineering [17], sports practice [18], textile industry [19], biomechanical [20], vibration isolation [21] and enhanced thermo-mechanical applications [22]. Silva et al [23] presented a comprehensive review on the chemical composition, and physical and mechanical properties of the cork material and signified its products and sub-products.…”

This manuscript aims to design and develop a 2D auxetic filtering medium with programmable geometric features specifically designed to vary under in-plane tensile strain. This feature empowers the filtering medium to control the particles separation. A novel design and optimisation algorithm developed in Matlab® determines the final optimized geometry of the filtering medium based on the desired particle size input. Upon thorough numerical investigation, an empirical relationship between the linear elastic in-plane tensile strain and aperture size of the proposed metamaterial is revealed. This empirical relation can be used in mechatronic and control systems to steer the proposed filtering medium. A prototype of such filtering medium capable of classification of particles of size 4mm to 4.5mm, when subjected to linear strain, is fabricated through Fused Deposition Modelling (FDM) process. The developed geometry configurations in this research are scalable, providing a potential cost-effective and efficient solution for industrial applications including reconfigurable filtration and segregation systems.

Designing efficient infrared illusions pose continuous hurdles, from complex operational circumstances to multiple heat distribution mechanisms and manufacturing intricacies. Most recent research efforts have been predominantly concentrated on tackling one issue at a time. In this chapter, we adopt a comprehensive approach by suggesting a kind of reconfigurable metasurface capable of illustrating an illusion in the infrared spectrum whilst preserving visible-light resemblance. The triadic essential modes of heat distribution are taken into consideration in the theoretical designs, with radiation-cavity effects being utilized in the practical construction process. Additionally, this study facilitates the concurrent modification of surface temperature and emissivity. Such metasurfaces prove their worth in fluctuating-temperature environments and transient situations. This summary not only underscores the potential of these adjustable metasurfaces in surmounting difficulties tied to thermal illusion design but also accentuates their flexibility and dependability in assorted settings.
