title = "Fabrication of graphene-based temperature sensors by flat-top femtosecond laser scribing phenolic resin",
abstract = "Temperature measurement plays a pivotal role in both everyday life and industrial production. The utilization of flexible temperature sensors has gained significant attention due to their exceptional flexibility, which allows for greater adaptability in various application environments. This paper introduces a straightforward and efficient approach to manufacturing a graphene-based flexible temperature sensor. Laser-induced graphene (LIG) was synthesized from phenolic resin (PR) irradiated by flat-top shaping femtosecond laser. The resulting LIG was thoroughly characterized using SEM, Raman spectroscopy, and XPS. The flexible temperature sensor was prepared based on LIG. The sensor has a sensitivity of 0.78% /°C and a linear response over a temperature range of 25-75°C. The application potential of PR-based LIG extends to human physiological health monitoring, wearable devices, and various other fields.",
