چکیده مقاله
Creating actively controlled air gaps within fabric structures represents a significant advantage over conventional insulation methods, enabling dynamic thermal insulation without increasing the weight or thickness of clothing This study investigates the use of shape memory alloy SMA wires, specifically Nitinol, integrated into fabric strips to achieve reversible and temperature responsive deformation Preliminary tests focused on the deformation behavior of the SMA wires and their integration into fabric samples, with wires trained under varying cycles and patterns Cooling tests to 45 °C demonstrated that trained wires formed predictable peak heights, and these deformations were effectively transferred to the fabric strips Samples with higher numbers of training cycles exhibited larger and more consistent deformation, while wires with fewer cycles induced slightly lower deformation in the fabric, highlighting the importance of proper training for optimal performance These results confirm the feasibility of using SMA wires to create dynamically adjustable fabric structures for enhanced thermal insulation Further investigations are currently underway to evaluate the actuation performance of the integrated fabrics under variable thermal conditions, and subsequent stages of the research will focus on quantitative thermal resistance measurements and the development of final smart garment prototypes
