由于在医疗领域、医疗保健和智能服装方面的各种应用，传感织物受到了极大的关注。然而，关于可用于监测压力衣压力的传感织物的研究很少。在这项研究中，通过使用工业规模的编织技术将高灵敏度的纱线传感器交织到机织织物中，制造了一种压力施加和传感织物。通过使用一种测量曲面外部应力下压力传感能力的新方法，评估了织物结构和操作模式对压力和机电性能的影响。提出了新的织物结构，以在织物内以较少或什至非结合的形式故意排列纱线传感元件，以获得良好的弹性和传感性能。由于合适的材料选择和结构特点，传感织物实现了合适和稳定的诱导压力以及非常低的应力松弛。因此，具有棉缎结构的传感织物表现出非常好的压力传感性能，灵敏度为 1.22 kPa^−1，8.06 % 的低滞后误差，在 0.58 至 3.83 kPa 的所需压力范围内线性度为 0.98。此外，该织物在 4500 次压制循环后表现出出色的稳定性。

Pressure and Electromechanical Behaviors of Elastic Pressure Exerting and Sensing Fabrics for Monitoring Pressure of Compression Textiles

Sensing fabrics have received great attention due to various applications in medical area, healthcare, and smart clothes. However, there are very few studies on sensing fabrics that can be used to monitor the pressure of compression garments. In this study, a pressure exerting and sensing fabric is fabricated by interweaving highly sensitive yarn sensor into woven fabric using industrial-scale weaving technology. By using a new method for measuring the pressure sensing capabilities under external stresses from a curved surface, effects of fabric structure and operation mode on the pressure and electromechanical properties are evaluated. New fabric structures are proposed to deliberately arrange the yarn sensing elements in a less- or even non-binding form within the fabric for good elasticity and sensing properties. Arising from the appropriate material selection and structure feature, the sensing fabric realizes a suitable and stable amount of induced pressure as well as very low stress relaxation. Consequently, the sensing fabric with sateen structure demonstrates very good pressure sensing performance with sensitivity of 1.22 kPa⁻¹, low hysteresis error of 8.06%, and linearity of 0.98 in the desired pressure range from 0.58 to 3.83 kPa. Furthermore, the fabric exhibits excellent stability over 4500 pressing cycles.
