Wireless graphene-enabled wearable temperature sensor

Abstract

Abstract E-textile is an emerging technology which takes the advantages of material science, electronic engineering and wireless communications. We present a pilot study on smart textile system. Our study aims at developing a graphene temperature sensor and its interfacing with a commercial wireless sensor node providing the graphene sensor with processing and wireless communication capabilities. Flexible planar structure sensor was fabricated using CVD-processed single-layer graphene following its transfer to the polyvinyl chloride substrate by hot lamination method. For calibrating the graphene temperature sensor we connect it in series with a calibrated resistor and to the calibrated power source (battery). Afterwards we measure the sensor resistance via the analogue-to-digital converter of wireless sensor node, process the data and send it to the user over wireless channel.
