The unique potential of e‐textiles for unobtrusive and ubiquitous monitoring and their innovative interfacing with electronic devices has garnished great attention. Sensors are one of the few essential devices or components necessary for most functional e‐textile applications. Ideally, any e‐textile based sensor should be soft, easily integrated in textile manufacturing processes, and tunable for the desired applications. Here, an easy‐to‐manufacture, tunable, fully‐textile sensor system with capability of detecting pressure, humidity, or wetness is presented. Capacitive pressure sensors are formed via a traditional sewing process with two commercially available conductive sewing yarns (silver‐plated polyamide (silver) and stainless steel (SS)) with cotton knit, polyethylene‐terephthalate (PET) knit and elastomeric meltblown textile dielectrics. The relationship between the sensor's physical, mechanical, and electromechanical properties including hysteresis, sensitivity, response, and relaxation time is evaluated. In addition, the same sensor configuration is assessed for its humidity and wetness sensing performance. Results indicate that pressure, relative humidity (RH), and wetness sensing performance are easily tunable using different combinations of the conductive and dielectric textile materials. Finally, proof of concept deployment demonstrations as human‐machine interfaces within a pressure sensing mat and a smart glove capable of remotely controlling a drone are provided.

全纺织品接缝线传感器,用于方便的纺织品集成和可调节的压力,湿度和湿度的多模态传感

电子纺织物用于无障碍且无处不在的监控的独特潜力及其与电子设备的创新接口已引起了极大的关注。传感器是大多数功能性电子纺织应用必不可少的必要设备或组件之一。理想情况下,任何基于电子纺织品的传感器都应该柔软,易于集成到纺织品制造过程中,并且可以针对所需应用进行可调。在此,提出一种易于制造,可调,全纺织的传感器系统,该系统具有检测压力,湿度或湿度的能力。电容式压力传感器是通过传统的缝纫工艺,由两根市售的导电缝纫线(镀银的聚酰胺(银)和不锈钢(SS)),棉线编织物,聚对苯二甲酸乙二醇酯(PET)编织物和弹性熔喷纺织电介质构成的。评估传感器的物理,机械和机电特性之间的关系,包括磁滞,灵敏度,响应和松弛时间。另外,评估了相同的传感器配置的湿度和湿度感测性能。结果表明,使用导电和绝缘纺织材料的不同组合,可以轻松调节压力,相对湿度(RH)和湿度感测性能。最后,提供了作为压力感应垫内的人机界面和能够远程控制无人机的智能手套的概念验证演示。评估相同的传感器配置的湿度和湿度感测性能。结果表明,使用导电和绝缘纺织材料的不同组合,可以轻松调节压力,相对湿度(RH)和湿度感测性能。最后,提供了作为压力感应垫内的人机界面和能够远程控制无人机的智能手套的概念验证演示。评估相同的传感器配置的湿度和湿度感测性能。结果表明,使用导电和绝缘纺织材料的不同组合,可以轻松调节压力,相对湿度(RH)和湿度感测性能。最后,提供了作为压力感应垫中的人机界面和能够远程控制无人机的智能手套的概念验证演示。
