Shape‐memory polymers (SMP) are materials responsive to stimuli, which will be modified to their initial form on the occurrence of an appropriate input. SMPs have been a class of impulsively valuable material in the last few decades. Because of their numerous, adaptable uses across a wide range, “wise” materials (SMPs) have attracted intense interest in the advanced material fields. Besides others, they need a substantial part of the area of the medical field. SMPs provide flexibility for promoting keyhole surgery, which offers stable strength, imposes stabilization forces, rinse therapeutic agents, and are degradable. Basic research on proposed SMP systems for medicine emphasizes biocompatibility, tolerability, disinfection, and non‐toxicity. This article mentions an overview of the latest advancements in the applications of SMP been reported. The article aims to incorporate all the possible applications of SMP, making it a versatile material that juxtaposes it with other advanced materials. The significance of SMP in the biomedical field, drug development, cardio‐vascular diseases, tissue engineering, wound dressing, surgical sutures, and many other applications has been highlighted. Another section dedicated to the antimicrobial abilities of SMP has been discussed. The last section is devoted to the conclusion and future developments in the respective area. Thus, this review focuses on many biomedicine areas and tube, medical science, and neuronic applications regarding the development and ability of SMPs to boost the quality of services in these fields.

“…Shape memory polymers (SMPs) are a class of smart materials that have gained attention due to their potential use in a variety of medical fields, including tissue, stents, drug delivery systems, and orthopaedic devices [1][2][3][4][5], thanks to their exceptional benefits including lightweight, affordability, versatility, and ease of processing [6,7]. The ability of SMPs to revert to their permanent shape after being subjected to an external stimulus, such as heat, solvent, pH, and a focused ultrasound (FU) field [8][9][10][11][12][13][14][15], is a key feature.…”

High-intensity focused ultrasound (HIFU) has been investigated as a remote and controlled activation method to noninvasively actuate shape memory polymers (SMPs), specifically in biomedical applications. However, the effects of aqueous environment on shape recoverability of in vivo HIFU-actuated SMPs have yet to be explored. HIFU directs sound waves into a millimeter-sized tightly focused region. In this study, the response of hydrophilic and hydrophobic photopolymerized thermoset SMP networks under HIFU activation in an aqueous environment was investigated. Acrylate-based SMP networks were copolymerized in specific ratios to produce networks with independently adjusted glass transition temperatures ranging from 40 to 80 °C and two distinct water uptake behaviors. The results link the polymer swelling behavior to shape recoverability in various acoustic fields. The presence of absorbed water molecules enhances the performance of SMPs in terms of their shape memory capabilities when activated by HIFU. Overall, understanding the interplay between water uptake and HIFU-actuated shape recovery is essential for optimizing the performance of SMPs in aqueous environments and advancing their use in various medical applications.

“…Shape memory polymers (SMPs) are "smart" materials that can restore their original shape from a deformed shape when exposed to an external stimulus [6,7]. Owing to versatility and low cost, SMPs are used to fabricate orthopedic devices [8], vascular stents [9], orthodontic wire for brackets [10], craniofacial meshes and plates [11], and neural probes [12].…”

The acceleration in advancements of smart materials and non-contact controlled devices in the field of 4D printing is facilitated by the use of magnetically responsive shape memory polymer (SMP) composites. This study is dedicated to the development of promising shape memory materials based on polylactic acid (PLA) and cobalt ferrite (CoFe2O4) nanoparticles. The activation of the shape memory effect (SME) in magnetic nanoparticle composites was achieved by applying a high-frequency alternating magnetic field (HFAMF). The PLA/CoFe2O4 composites exhibited a remarkable shape recovery ratio (>84%) and underwent rapid heating when exposed to HFAMF. The interaction of these composites with mouse adipose-derived mesenchymal stem cells demonstrated adequate cytocompatibility. The rapid magnetosensitive behavior and high shape recovery characteristics of PLA/CoFe2O4 composites make them promising candidates for biomedical applications.
