Temperature and moisture are critical factors for both the environment and living creatures. Most temperature sensors and humidity sensors are rigid. It still remains an unsolved problem to fabricate a flexible sensor that can easily detect temperature and humidity at the same time. In this work, we made a flexible multifunctional temperature and humidity sensor from graphene woven fabrics. The integrated sensor could measure temperature and humidity simultaneously. The temperature-sensing part and the humidity-sensing part were stacked in layer structure, occupying little space and showing good flexibility while exhibiting high sensitivity and very little mutual interference. The different factors that affected the sensing properties of the sensor were examined. The integrated sensor was successfully utilized in several real life application scenarios, which showed its potential for wider use in environment sensing and health monitoring.
