Graphene-based wearable temperature sensors: A review

Abstract

The paper presents a comprehensive review of the use of graphene to develop wearable temperature sensors. The detection of temperature over a wide range has been a growing interest in multidisciplinary sectors in the sensing world. Different kinds of flexible temperature sensors have been fabricated with a range of polymers and nanomaterials. With the additional attribute of wearable nature, these temperature sensors are used ubiquitously to determine the effect of physiochemical variations happening in the environment of the chosen biomedical and industrial applications. Graphene, owing to its exceptional electrical, mechanical, and thermal properties, has been extensively used for the development of wearable temperature sensors. The prototypes have been deployed with certain wireless communication protocols to transfer the experimental data obtained under both controlled environments and real-time scenarios. This paper underlines some of the significant works done on the use of graphene to fabricate and implement wearable temperature sensors, along with the possible remedial steps that can be considered to deal with the challenges existing in the current literature.
