摘要

柔性压力传感器（fps）引起了研究人员的极大兴趣，他们专注于运动识别、医疗保健、康复治疗、运动表现监测等可穿戴电子产品的应用。近年来，以其灵活性和舒适性而闻名的织物已成为制造各种柔性传感器的热门基材。在这些柔性传感器中，压阻式器件因其简单和对物理运动的显著敏感性而受到青睐。本研究采用简单滴涂法，在粘胶短纤维/亚麻混纺织物上涂覆功能化导电炭黑（CB），制备了一种复合织物，并对其感压性能进行了评价。在0 ~ 1 kPa和1 ~ 20 kPa压力范围内，CB含量最优的FPS灵敏度分别为41.1 kPa ${}^{\mathbf{-1}}$和1.4 kPa ${}}^{\mathbf{-1}}$。低检测限为10 Pa，响应时间为16 ms，松弛时间为63 ms，耐久性超过5400次，在各种环境条件下性能稳定，FPS在弯曲运动监测和信息传输方面具有潜在的应用前景。

Carbon Black-Coated Fabric Blend as Piezoresistive Flexible Pressure Sensor for Motion Monitoring Applications

Flexible pressure sensors (FPSs) have garnered significant interest among researchers focusing on wearable electronics for motion recognition, health care, rehabilitation therapy, athletic performance monitoring, and more applications. Recently, fabrics known for their flexibility and comfort have become popular substrates for fabricating various flexible sensors. Of these flexible sensors, piezoresistive devices are favored for their simplicity and notable sensitivity to physical movements. This study presents a fabric composite created by coating a viscose staple fiber/linen blend with functionalized conductive carbon black (CB) using a simple drop-coating method and evaluates its pressure-sensing performance. The FPS with optimum CB content exhibited sensitivities of 41.1 kPa

${}^{\mathbf {-1}}$

and 1.4 kPa

${}^{\mathbf {-1}}$

in the pressure ranges of 0-1 kPa and 1-20 kPa, respectively. With a low detection limit of 10 Pa, a response time of 16 ms, a relaxation time of 63 ms, durability exceeding 5,400 cycles, and stable performance in various ambient conditions, the FPS has exhibited potential for applications in bending motion monitoring and information transmission.

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
