Women sports wearer's comfort and health are greatly impacted by the breast movements and resultant sports bra compression to prevent excessive movement. However, as sports bras are only made in universal sizes, they do not offer the right kind of support that is required for a certain activity. To prevent this issue, textile-based strain sensors may be utilized to track compression throughout various activities to create activity-specific designed sports bras. Textile-based strain sensors are prepared in this study using various conductive yarns, including steel, Ag-coated polyamide, and polypropylene/steel-blended threads. Various embroidery designs, including straight, zigzag, and square-wave embroidery patterns, etc., were created on knitted fabric and characterized for strain sensing efficiencies. The experiments concluded that strain sensors prepared from polypropylene/steel thread using a 2-thread square-wave design were best performed in terms of linear conductivity, sensitivity of mechanical impact, and wide working range. This best-performed sample was also tested by integrating it into the sportswear for proposed compression measurements in different body movements.
女性运动时乳房的活动以及由此产生的运动胸罩的压迫，对防止过度运动至关重要，会极大地影响女性运动服装穿着者的舒适度和健康状况。然而，由于运动胸罩仅采用通用尺寸制作，它们无法为特定活动提供所需的合适支撑。为解决这一问题，可利用基于纺织品的应变传感器来跟踪各种活动中的压迫情况，以制作针对特定活动设计的运动胸罩。本研究使用包括钢、镀银聚酰胺和聚丙烯/钢混纺线在内的各种导电纱线制备基于纺织品的应变传感器。在针织物上创建了各种刺绣图案，包括直线、之字形和方波刺绣图案等，并对其应变传感效率进行了表征。实验得出结论，采用双股线方波设计由聚丙烯/钢线制备的应变传感器在线性导电性、机械冲击灵敏度和宽工作范围方面表现最佳。还通过将这个性能最佳的样品集成到运动服装中，对不同身体动作中的压迫情况进行测量，对其进行了测试。
