In recent years, wearable technologies have attracted great attention in physical and chemical sensing applications. Wearable pressure sensors with high sensitivity in low pressure range (<10 kPa) allow touch detection for human-computer interaction and the development of artificial hands for handling objects. Conversely, pressure sensors that perform in a high pressure range (up to 100 kPa), can be used to monitor the foot pressure distribution, the hand stress during movements of heavy weights or to evaluate the cyclist's pressure pattern on a bicycle saddle. Recently, we developed a fully textile pressure sensor based on a conductive polymer, with simple fabrication and scalable features. In this paper, we intend to provide an extensive description on how the mechanical properties of several fabrics and different piezoresistive ink formulation may have an impact in the sensor's response during a dynamic operation mode. These results highlight the complexity of the system due to the presence of various parameters such as the fabric used, the conductive polymer solution, the operation mode and the desired pressure range. Furthermore, this work can lead to a protocol for new improvements and optimizations useful for adapting textile pressure sensors to a large variety of applications.
近年来，可穿戴技术在物理和化学传感应用中引起了极大的关注。具有在低压力范围（<10kPa）下高灵敏度的可穿戴压力传感器允许用于人机交互的触摸检测和用于处理物体的人工手的发展。相反，在高压力范围（高达 100kPa）下工作的压力传感器可用于监测足部压力分布、重物运动期间手部的压力、或评估自行车鞍座上自行车骑手的压力模式。最近，我们开发了一种基于导电聚合物的全纺织压力传感器，具有简单的制造和可扩展的特点。在本文中，我们旨在提供广泛的描述，说明几种织物的机械性能和不同压阻油墨配方如何在传感器的动态操作模式下对其响应产生影响。这些结果突出了系统的复杂性，因为存在各种参数，例如所使用的织物、导电聚合物溶液、操作模式和所需的压力范围。此外，这项工作可以为新的改进和优化提供一个方案，有助于将纺织压力传感器适应各种应用。
