Temperature-dependent shape-memory textiles : physical principles and applications

Abstract

Textiles have been pivotal to economies and social relationships throughout history. In today’s world, there is an unprecedented demand for smart materials. The advent of smart textile fabrics, crafted from high-quality, high-performance fibers, has enabled the incorporation of specific functions into clothing and apparel brands. Notably, the rise of smart fabrics is evident in astronaut suits designed to regulate temperature and control muscle vibrations. Moreover, the scope of these products has expanded beyond everyday wear, encompassing fields such as medicine and healthcare, ecology/environmental protection, and military and aerospace. This review explores the recent advancements and challenges associated with intelligent fabrics, particularly temperature-dependent shape-memory metamaterials. The potential for innovative smart textile materials to enhance traditional fabrics’ overall functionality and utility is immense, especially in domains such as medical devices, fashion, entertainment, and defense. Crucially, ensuring user comfort is a primary consideration in these applications for promoting the widespread adoption of wearable devices. Developing smart textile devices necessitates a multidisciplinary approach that combines circuit design expertise, knowledge of smart materials, proficiency in microelectronics, and a deep understanding of chemistry and textile production. The synergy across these diverse fields is vital to unlocking the full potential of smart fabrics and enabling their broad implementation. By embracing this comprehensive approach, we can pave the way for groundbreaking advances in smart textile technology, driving innovation and progress in the field.
