Graphene Flexible Temperature Sensing Unit and Its Reliability
This paper investigates the fabrication process and performance characteristics of graphene-based flexible temperature sensors.The working mechanism of graphene flexible temperature sensors is first elaborated,followed by an exploration of the sensor unit fabrication method using polydimethylsiloxane as the substrate material and graphene as the conductive medium.Through optimization of graphene paste formulation and screen printing technology,flexible temperature sensing units were successfully fabricated.Subsequently,systematic performance tests were conducted on the sensing units,including resistance-temperature characteristic analysis and temperature cycling stability evaluation.Experimental results demon-strate that the fabricated sensing units exhibit excellent performance in terms of resistance-temperature characteristics and cycling stability,showing potential for industrial-grade applications.This study provides important technical support for the practical application of graphene flexible temperature sensors.
