The significance of advanced smart materials in recent technological research and advancement is apparent from its extensive use in present day devices and instruments. Of the various smart materials in use today, the fascinating category of shape memory alloys (SMAs) is equipped with the ability to return to a previously memorized shape under certain thermomechanical or magnetic stimuli. The unique property of shape memory effect and superelasticity displayed by these materials along with good biocompatibility and corrosion resistance make them ideal for biomedical applications. The various applications of SMAs in surgical instruments, surgical implants, and assistive and rehabilitative devices have significant effect on the day to day life of people in the present age. Majority of these biomedical devices belong to the orthodontic, orthopedic, or surgical fields. Other remarkable applications of SMAs such as in the production of prostheses and orthoses designed through the biomimetic approach are also highly influential in improving the quality of life. The present paper provides an overview of the various properties of shape memory alloys and their applications in the biomedical field over the years, that have had a significant impact on the realm of medical science.
先进智能材料在当今技术研究和发展中的重要性显而易见，它广泛应用于当今的设备和仪器中。在当今使用的各种智能材料中，引人入胜的形状记忆合金 (SMA) 类别具有在特定热机械或磁刺激下恢复到先前记忆形状的能力。这些材料表现出的形状记忆效应和超弹性的独特特性，以及良好的生物相容性和耐腐蚀性，使它们成为生物医学应用的理想选择。SMA 在手术器械、手术植入物以及辅助和康复设备中的各种应用对当今人们的日常生活产生了重大影响。这些生物医学设备大多数属于正畸、骨科或外科领域。SMA 的其他显著应用，如通过仿生方法设计的假肢和矫形器的生产，也在提高生活质量方面具有重要影响。本文概述了形状记忆合金的各种特性及其多年来在生物医学领域的应用，这些应用对医学领域产生了重大影响。
