纺织品和电子元件是大多数可穿戴技术（可穿戴设备）的关键要素；根据使用、保养和用户操作等因素，这两种组件的老化速度不同。这些组件的机械性能特征 (MPC)（即磨损、伸长率和破裂强度）的差异给研究人员和产品设计师开发以用户为中心的经济型可穿戴设备带来了挑战。例如，由尼龙/氨纶针织混纺制成的运动可穿戴设备表现出与最小纤维含量变化 (1-10%) 截然不同的 MPC。然而，可穿戴设备的最终用途保持不变。本文介绍了测试 MPC 的想法和方法以及如何评估不同最终用例的结果。针对最终用户活动的设计也突出了这些性能差异，因为特定的最终用途驱动纺织品设计，这可能是也可能不是可穿戴设计的最终用途。采用三种美国材料试验协会（ASTM）测试方法对运动面料和软体机器人传感器（SRS）的MPC进行测试，以确定这些部件的耐磨性、伸长率和顶破强度，并对结果进行双尾ttest比较。 SRS 的耐用性低于它们所集成的纺织品，而且由于没有 SRS 的 MPC 测试标准，因此尚不清楚传感器的使用寿命有多长。需要开发此类方法，以便产品开发人员能够找到纤维和电子元件的有效组合，以确保以用户为中心的功能、佩戴者的舒适度、延长产品的使用寿命和总体消费者满意度。
Textile and electronic components are critical elements of most wearable technologies (wearables); both components deteriorate at different rates depending on factors of use, care, and user handling. The differences in mechanical performance characteristics (MPC) (i.e., abrasion, elongation, and bursting strength) of these components create a challenge for researchers and product designers to develop user-centric and economical wearables. For example, athletic wearables made of nylon/spandex knit blends exhibit drastically different MPC from minimal fiber content changes (1- 10%). However, the wearable's end-use remains constant. This article presents ideas and methods for testing MPC and how to evaluate results for different end-use cases. Designing for end-user activities also highlights these performance differences because specific, end-uses drive textiles design, which may or may not be the wearable design's end-use. Three American Society for Testing and Materials (ASTM) test methods were used to test MPC of athletic fabrics and soft robotic sensors (SRS) to determine the abrasion resistance, elongation, and bursting strength of these components and two-tail ttest comparisons were performed on the results. The SRS's durability is less than the textiles they are integrated into, and with no standards for MPC testing on SRS, it can be unclear how long a sensor will last. Such methods need to be developed so product developers can find efficient combinations of fibers and electronic components to ensure user-centric functionality, wearer comfort, extended product longevity, and overall consumer satisfaction.
