Deployable structure, aerospace, medical devices, emergency facilities
Abstract
Deployable structures have become vital in various fields due to their ability to transition between compact and expanded forms. This study focuses on their applications in aerospace engineering, medical devices, and emergency facilities. In aerospace, deployable structures like antennas and solar panels optimize space and functionality. Medical devices, particularly stents and retractable instruments, use deployable designs to enhance minimally invasive procedures. Emergency facilities, such as deployable bridges and shelters, offer rapid, reliable solutions in disaster and military contexts. The research highlights significant advancements, e.g., scissor-like mechanisms in deployable bridges, origami-based solar panels, and NiTi shape-memory alloy stents. Despite progress, challenges remain in improving durability and simplifying deployment processes. Future research should focus on lightweight, durable materials and simplified designs to enhance reliability and expand the range of applications. The significance lies in providing a comprehensive review of deployable structures, analyzing both their benefits and limitations, and offering insights into potential future developments that could influence engineering, healthcare, and emergency response innovations.
