“…They studied highly idealized vascular scaffolds, as shown in Figure 35(c), which are examined using 3D printing technology and forming techniques, namely nozzles, printing settings, printing routes, and rheological characteristics, to improve structural quality. Yuyang et al 222 reported that self-healing materials could also be printed using vat photopolymerization using polyurethane acrylate-based photopolymer resin with linkages of disulfide. Studies on self-healing smart structures of vascular-network have gained popularity.…”

The biomimetic approach rapidly evolves for designing novel lightweight structures and has been expanding in engineering design. Additive manufacturing or 3D printing permits three-dimensional parts to be fabricated with an intricacy and quality that might be tough or impossible to appreciate with the present traditional production techniques. With the probabilities and exactitude, 3D printing allows bio-inspired lattice structures from nature that are hypothetically advanced to ingest excellent energy absorption capacity with less material. The combination of additive manufacturing with cellular lattice architectures offers potential design options regarding material utilization, strength, cost, and component weight. A summary of recent advances in the improvement of bio-inspired structures is outlined in this review paper. Specifically, exciting highlights and remarkable mechanical properties of bio-inspired structures of bones, teeth, and dermal layers of creatures might be bio-mimicked to style economical energy absorbers. Researchers and engineers can use this information to create unique designs inspired biologically for the application of absorption energy.

“…Hydrogels with controllable swelling are therefore a promising avenue for developing shape-changing devices. This is particularly true at small scales, where recent technological advances allow for micro-scale design and manufacture of gel structures through techniques such as three-dimensional printing via two-photon polymerisation, otherwise known as 2PP (Hippler et al 2019;Ji et al 2021), and halftone gel or stop flow lithography (Kim et al 2012;Sharan et al 2021). Such small devices have a wide range of physical applications (Ionov 2014), for example as microfluidic valves (Harmon, Tang & Frank 2003;Richter et al 2003), as grippers that could be used by soft robots (Li et al 2017), and as actuation for swimming in microbots or artificial active matter (Masoud, Bingham & Alexeev 2012;Nikolov, Yeh & Alexeev 2015;Mourran et al 2017;Montenegro-Johnson 2018;Wischnewski & Kierfeld 2020).…”

Thermo-responsive hydrogels are a promising material for creating controllable actuators for use in micro-scale devices, since they expand and contract significantly (absorbing or expelling fluid) in response to relatively small temperature changes. Understanding such systems can be difficult because of the spatially and temporally varying properties of the gel, and the complex relationships between the fluid dynamics, elastic deformation of the gel and chemical interaction between the polymer and fluid. We address this using a poro-elastic model, considering the dynamics of a thermo-responsive spherical hydrogel after a sudden change in the temperature that should result in substantial swelling or shrinking. We focus on two model examples, with equilibrium parameters extracted from data in the literature. We find a range of qualitatively different behaviours when swelling and shrinking, including cases where swelling and shrinking happen smoothly from the edge, and other situations that result in the formation of an inwards-travelling spherical front that separates a core and shell with markedly different degrees of swelling. We then characterise when each of these scenarios is expected to occur. An approximate analytical form for the front dynamics is developed, with two levels of constant porosity, that well-approximates the numerical solutions. This system can be evolved forward in time, and is simpler to solve than the full numerics, allowing for more efficient predictions to be made, such as when deciding dosing strategies for drug-laden hydrogels.
