Flexible, breathable, and highly sensitive pressure sensors have increasingly become a focal point of interest due to their pivotal role in healthcare monitoring, advanced electronic skin applications, and disease diagnosis. However, traditional methods, involving elastomer film-based substrates or encapsulation techniques, often fall short due to mechanical mismatches, discomfort, lack of breathability, and limitations in sensing abilities. Consequently, there is a pressing need, yet it remains a significant challenge to create pressure sensors that are not only highly breathable, flexible, and comfortable but also sensitive, durable, and biocompatible. Herein, we present a biocompatible and breathable fabric-based pressure sensor, using nonwoven fabrics as both the sensing electrode (coated with MXene/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate [PEDOT:PSS]) and the interdigitated electrode (printed with MXene pattern) via a scalable spray-coating and screen-coating technique. The resultant device exhibits commendable air permeability, biocompatibility, and pressure sensing performance, including a remarkable sensitivity (754.5 kPa⁻¹), rapid response/recovery time (180/110 ms), and robust cycling stability. Furthermore, the integration of PEDOT:PSS plays a crucial role in protecting the MXene nanosheets from oxidation, significantly enhancing the device's long-term durability. These outstanding features make this sensor highly suitable for applications in full-range human activities detection and disease diagnosis. Our study underscores the promising future of flexible pressure sensors in the realm of intelligent wearable electronics, setting a new benchmark for the industry.

采用生物相容性 MXene/PEDOT:PSS 复合材料实现超灵敏压力传感的个性化电子纺织品

灵活、透气、高灵敏度的压力传感器因其在医疗保健监测、先进电子皮肤应用和疾病诊断中的关键作用而日益成为人们关注的焦点。然而，涉及基于弹性体薄膜的基材或封装技术的传统方法常常由于机械不匹配、不适、缺乏透气性以及传感能力的限制而达不到要求。因此，创造不仅高度透气、灵活、舒适，而且灵敏、耐用和生物相容的压力传感器仍然是一个迫切的需求，但仍然是一个重大挑战。在此，我们提出了一种生物相容性和透气性的基于织物的压力传感器，使用无纺布作为传感电极（涂有 MXene/聚（3,4-乙烯二氧噻吩）：聚苯乙烯磺酸盐 [PEDOT:PSS]）和叉指电极（印刷MXene 图案）通过可扩展的喷涂和丝网涂层技术。所得装置表现出值得称赞的透气性、生物相容性和压力传感性能，包括卓越的灵敏度（754.5 kPa ^-1）、快速响应/恢复时间（180/110 ms）和强大的循环稳定性。此外，PEDOT:PSS 的集成在保护 MXene 纳米片免受氧化方面发挥着至关重要的作用，从而显着提高了设备​​的长期耐用性。这些突出的特性使得该传感器非常适合全方位人体活动检测和疾病诊断的应用。我们的研究强调了柔性压力传感器在智能可穿戴电子领域的广阔前景，为行业树立了新的基准。
