电子纺织品在不引人注目和无处不在的监测方面的独特潜力及其与电子设备的创新接口引起了极大的关注。传感器是大多数功能性电子纺织品应用所需的少数基本设备或组件之一。理想情况下，任何基于电子纺织品的传感器都应该是柔软的，易于集成在纺织制造过程中，并且可以根据所需的应用进行调整。在这里，一个易于制造，可调，全纺织传感器系统，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，用两种市售的导电缝纫纱线（镀银聚酰胺（银）和不锈钢（SS））与棉针织、聚对苯二甲酸乙二醇酯（PET）针织和弹性体熔喷纺织电介质制成的。评估了传感器的物理、机械和机电性能之间的关系，包括滞后、灵敏度、响应和松弛时间。此外，对相同传感器配置的湿度和湿度传感性能进行了评估。结果表明，使用不同的导电和介电纺织材料组合，可以很容易地调节压力、相对湿度（RH）和湿度传感性能。最后，提供了概念验证部署演示，如压力传感垫内的人机界面和能够远程控制无人机的智能手套。
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.
