Pressure sensor, as one of the most common components in the sensing systems, has attracted plenty of attention in recent years with urgent needs. Herein, a highly sensitive flexible pressure sensor based on conducting polymer (CP)-coated paper is developed via an ultra-simple approach of synthesis and fabrication. This paper-based sensor displays an ultra-low detection limit as low as 0.3 Pa level, and outstanding sensitivity (∼2 kPa⁻¹, P ≤ 75 Pa), which can rank the top among that of the reported pressure sensors. The advantages based on paper framework such as low cost, portability, and easy disposability further enhance its feasibility. Meanwhile, combining its rapid and precise response at room temperature and the recognized stability of PPy in the ambient environment, the sensor would ensure direct and continuous environment monitoring with low energy consumption.

压力传感器作为传感系统中最常见的组件之一，近年来迫切需要引起人们的广泛关注。本文中，通过超简单的合成和制造方法，开发了一种基于导电聚合物（CP）涂层纸的高灵敏柔性压力传感器。这种基于纸张的传感器显示出低至0.3 Pa的超低检测限，并具有出色的灵敏度（〜2 kPa ^-1，P ≤75 Pa），可以在报告的压力传感器中名列前茅。基于纸质框架的优点包括低成本，可移植性和易处理性，进一步增强了其可行性。同时，结合其在室温下的快速精确响应以及公认的PPy在周围环境中的稳定性，该传感器将确保以低能耗进行直接和连续的环境监测。
