摘要

湿度传感器已广泛应用于日常生活、农业等领域的湿度监测。然而，传统的传感器由于其大尺寸和刚性衬底而不适合可穿戴设备。因此，我们报道了一种基于还原氧化石墨烯/MoS2复合材料的PI衬底上的快速响应、高灵敏度和全柔性湿度传感器，在11% RH - 95% RH的相对湿度范围内，响应时间为0.65 s，灵敏度为96.7%。将所制备的柔性湿度传感器与柔性印刷电路集成，实现了全柔性可穿戴设备，并成功应用于人体呼吸监测、运动监测和非触摸开关等领域。这些结果表明，rGO/MoS2复合材料是湿度传感的良好候选材料，具有应用于可穿戴设备和非触摸开关领域的潜力。

Fully Flexible Humidity Sensor with Fast Response and High Responsivity Based on rGO/MoS2 for Human Respiration Monitoring and Nontouch Switches

Humidity sensors have been widely used to monitor humidity in daily life, agriculture fields, and so on. However, conventional sensors are not suitable for wearable devices because of their large dimensions and rigid substrates. Hence, we report a fast response, highly sensitive, and fully flexible humidity sensor on a PI substrate based on the composite material of reduced graphene oxide (rGO)/MoS₂, with a response time of 0.65 s and a sensitivity of 96.7% in the relative humidity range of 11% RH–95% RH. A fully flexible wearable device was realized by integrating the prepared flexible humidity sensor with a flexible printed circuit, which was successfully applied for human breathing monitoring, motion monitoring, and nontouch switches. These results show that the rGO/MoS₂ composite is a good candidate for humidity sensing and has the potential to be used in the fields of wearable devices and nontouch switching.

期刊介绍： ACS Applied Materials & Interfaces is a leading interdisciplinary journal that brings together chemists, engineers, physicists, and biologists to explore the development and utilization of newly-discovered materials and interfacial processes for specific applications. Our journal has experienced remarkable growth since its establishment in 2009, both in terms of the number of articles published and the impact of the research showcased. We are proud to foster a truly global community, with the majority of published articles originating from outside the United States, reflecting the rapid growth of applied research worldwide.
