Wireless Graphene Temperature Sensor

We demonstrate a sensitive wearable temperature sensor integrated with graphene electrodes on a flexible polyvinyl chloride substrate. The polymer-assisted transfer method of graphene provides a facile and cost-effective way for sensor fabrication. The graphene-enabled temperature sensor demonstrates good performance and opportunity of extending its functionality with processing and wireless communication features. This assigned to the excellent flexibility, stability to the ambient conditions, and thermal sensitivity within the human body temperature range. The fabricated sensor is feasible for temperature monitoring in real-time and sending the measured data at 2.4 GHz over wireless network. Such wearable graphene-enabled sensor with processing and wireless communication capabilities is vital for the new generation healthcare control and human-machine interface systems.
