In the contemporary era, novel manufacturing technologies like additive (AM) have revolutionized different engineering sectors including biomedical, aerospace, electronics, etc. Four-dimensional (4D) printing aka AM of smart materials is gaining popularity among scientific community, which has excellent ability to make soft structures such as robots, actuators, and grippers. These are developed by applying various stimuli pH, temperature, magnetic field, many combinations onto materials. Stimuli in 3D permit shape-morphing behaviors bending, twisting, folding, swelling, rolling, shrinking, origami, or locomotion. A wide variety can be fabricated through incorporation hard particles into resulting magneto-active (MASMs). With this integration, magneto-thermal coupling actuation allows diverse magneto-deformations, facilitating development personalized devices that capable enhanced deformation. review, guidelines provided on for MASMs polymers (MAPs), composites, hydrogels (MAHs) booming flexible wearable biomimetic devices. Moreover, 3D-printed robotics an outstanding capacity adapt complicated situations advanced actuating applications. Finally, some current challenges emerging areas exciting technology been proposed. Lastly, it anticipated technological advancements developing intelligent will a significant impact design real-world

In this review, today's state of the art in rheology gels and transition through yield stress yielding liquids is discussed. Gels are understood as soft viscoelastic multicomponent solids that incomplete phase separation state, which, under action external mechanical forces, do not transit into a fluid but rupture like any solid material. can "melt" (again, solids) due to change temperature or variation environment. contrast type rheology, (sometimes rigorously referred "gels", especially relation colloids) exist solid-like (gel-like) become above some defined time conditions (yield stress). At low stresses, their behavior quite similar permanent gels, including frequency-independent storage modulus. The gel-to-sol considered colloid chemistry treated case yielding. However, many cases, cannot be assumed physical parameter since solid-to-liquid happens associated with thixotropic effects. special attention paid various It also stressed plasticity equivalent flow (irreversible) plastic deformations determined by continue over time. We discuss typical errors, difficulties, wrong interpretations experimental data studies liquids.

Hydrogels are widely used biomaterials in the delivery of therapeutic agents, including drugs, genes, proteins, etc., as well tissue engineering, due to obvious properties such biocompatibility and their similarity natural body tissues. Some these substances have feature injectability, which means that substance is injected into desired place solution state then turns gel, makes it possible administer them from a way with minimal amount invasion eliminate need for surgery implant pre-formed materials. Gelation can be caused by stimulus and/or spontaneously. Suppose this induces effect one or many stimuli. In case, material question called stimuli-responsive because responds surrounding conditions. context, we introduce different stimuli cause gelation investigate mechanisms transformation gel them. Also, study special structures, nano gels nanocomposite gels.
