Development of Graphene-Based Flexible Thermocouples for Wearable Applications

This paper presents a novel graphene-based thermocouple that utilizes PVDF/GNP nanocomposites casted over commercial fabrics and characterized by outstanding electrical and thermal properties while maintaining flexibility, chemical stability, and corrosion resistance. The proposed thermocouple has performance comparable to that of commercially available K-type, generating an output voltage of 33.9 $\text{pV}/\mathrm{K}$ and providing accurate temperature measurement for various applications. Additionally, the flexibility and corrosion resistance of the thermocouples described make them more durable and versatile than traditional ones. Overall, this innovative thermocouple represents a significant advancement in the field of temperature measurement technology.
