With the rapid development of medical technology and increasing demands for healthcare monitoring, wearable temperature sensors based on reduced graphene oxide (rGO) have attracted widespread attention. This is due to their portability, flexibility, and ability to conduct real-time and continuous signal detection. The exceptional thermal conductivity and sensitive resistance changes of rGO make it an ideal material for temperature sensors. This paper reviews the state-of-the-art advances in rGO-based wearable temperature sensors, including their sensing mechanisms, structure designs, functional material additions, manufacturing processes, and performances.
With the development of medical technology and increasing demands of healthcare monitoring, wearable temperature sensors have gained widespread attention because of their portability, flexibility, and capability of conducting real-time and continuous signal detection. To achieve excellent thermal sensitivity, high linearity, and a fast response time, the materials of sensors should be chosen carefully. Thus, reduced graphene oxide (rGO) has become one of the most popular materials for temperature sensors due to its exceptional thermal conductivity and sensitive resistance changes in response to different temperatures. Moreover, by using the corresponding preparation methods, rGO can be easily combined with various substrates, which has led to it being extensively applied in the wearable field. This paper reviews the state-of-the-art advances in wearable temperature sensors based on rGO films and summarizes their sensing mechanisms, structure designs, functional material additions, manufacturing processes, and performances. Finally, the possible challenges and prospects of rGO-based wearable temperature sensors are briefly discussed.
