截肢者在佩戴假肢设备时容易感到不适。随着截肢者人数的增加，这变得更加普遍和紧迫。需要新的假体技术来构建更舒适和更合适的衬垫和插座。新假体技术发展的一个众所周知的障碍是缺乏实用的内窝传感器来监测内窝环境(ISE)，即残肢和窝之间的区域。在这里，我们提出了一种电容式压力传感器，通过一种简单的、可伸缩的缝制工艺，使用商业上可获得的导电纱线和纺织材料来制造。这种全纺织品传感器为监控ISE提供了一个柔软、灵活和舒适的传感系统。我们提供了我们的低功耗传感器系统的详细信息，该系统能够从多达四个传感器阵列进行高速数据收集。此外，我们还演示了两种定制设置，以在模拟假肢环境中测试和验证基于纺织品的传感器。最后，我们利用基于纺织品的传感器来研究一个双侧经胫骨截肢者的ISE。结果表明，基于纺织品的传感器在无缝监测ISE方面具有广阔的应用前景。
Amputees are prone to experiencing discomfort when wearing their prosthetic devices. As the amputee population grows this becomes a more prevalent and pressing concern. There is a need for new prosthetic technologies to construct more comfortable and well-fitted liners and sockets. One of the well-recognized impediments to the development of new prosthetic technology is the lack of practical inner socket sensors to monitor the inner socket environment (ISE), or the region between the residual limb and the socket. Here we present a capacitive pressure sensor fabricated through a simple, and scalable sewing process using commercially available conductive yarns and textile materials. This fully-textile sensor provides a soft, flexible, and comfortable sensing system for monitoring the ISE. We provide details of our low-power sensor system capable of high-speed data collection from up to four sensor arrays. Additionally, we demonstrate two custom set-ups to test and validate the textile-based sensors in a simulated prosthetic environment. Finally, we utilize the textile-based sensors to study the ISE of a bilateral transtibial amputee. Results indicate that the textile-based sensors provide a promising potential for seamlessly monitoring the ISE.
