Aerosol jet printing of nickel oxide nanoparticle ink with ultraviolet radiation curing for thin-film temperature sensors

In this study, the ultraviolet (UV) radiation curing process and furnace for aerosol jet printed nickel oxide (NiO) nanoparticle thin films were investigated. NiO has a negative temperature coefficient can be used to fabricate sensors. Four UV power settings (for 10 min) four temperatures 1 h) cure The resultant sensor resistance at 100 °C 180 was measured, sensor’s sensitivity characterized by B value. Confocal microscopy performed characterize surface. 60% setting yields lowest highest value among all analysis of variations shows that is not significant factor in value, while factor. This indicates more robust method does need optimized achieve good results. only reduces required time but also improves performance sensor.
