Paper, as a flexible, low-cost, lightweight, tailorable, environmental-friendly, degradable, and renewable material, is emerging in electronic devices. Especially, many kinds of paper-based (PB) sensors have been reported for wearable applications in recent years. Among them, the PB gas, humidity, and strain sensors are widely studied for monitoring gas, humidity, and strain from the human body and the environment. However, gas, humidity, and strain often coexist and interact, and the paper itself is hydrophilic and flexible, resulting in that it is still challenging to develop high-performance PB sensors specialized for gas, humidity, and strain detections. Therefore, it is necessary to summarize and discuss them systematically. In this review, we focus on summarizing the state-of-art studies of the PB gas, humidity, and strain sensors. Specifically, the fabrications (electrodes and sensing materials) and applications of PB gas, humidity, and strain sensors are summarized and discussed. The current challenges and the potential trends of PB sensors for gas, humidity, and strain detections are also outlined. This review not only can help readers to understand the development status of the PB gas, humidity, and strain sensors but also is helpful for readers to find out and solve the problems in this field through comparative reading.
纸张作为一种灵活、低成本、轻质、可定制、环保、可降解且可再生的材料，正在电子设备领域崭露头角。特别是近年来，已经报道了多种用于可穿戴应用的纸基（PB）传感器。其中，PB气体、湿度和应变传感器被广泛研究用于监测人体和环境中的气体、湿度和应变。然而，气体、湿度和应变常常共存且相互作用，并且纸张本身具有亲水性和柔韧性，这使得开发专门用于气体、湿度和应变检测的高性能PB传感器仍然具有挑战性。因此，有必要对它们进行系统的总结和讨论。在这篇综述中，我们专注于总结PB气体、湿度和应变传感器的最新研究。具体而言，总结并讨论了PB气体、湿度和应变传感器的制备（电极和传感材料）及应用。还概述了PB传感器在气体、湿度和应变检测方面当前面临的挑战以及潜在的发展趋势。这篇综述不仅可以帮助读者了解PB气体、湿度和应变传感器的发展现状，还有助于读者通过对比阅读发现并解决该领域的问题。
