One of the major identified challenges in the printed electronics industry currently is the ability to match this manufacturing capability for printed resistors in terms of initial tolerance, stability over time and power capabilities. In this work, a variety of screenprinted carbon resistors were designed and produced. The effects of utilising additional screenprinted ZnO and Ag layers as thermal variance management for the carbon resistors are investigated with the aim of improving the resistors power rating and stability. The introduction of ZnO or ZnO/Ag layers to carbon resistors saw notable improvements in the peak power capability, stability when sustaining 500mW power dissipation, and stability in varying environmental conditions. Utilizing ZnO and Ag layers also notably improved the initial tolerance groupings when compared to basic uncoated carbon resistors. 2020-10-01T00:00:00Z Text Journal contribution 2134/12998720.v1 https://figshare.com/articles/journal_contribution/Printed_resistors_for_flexible_electronics_thermal_variance_mitigation_and_tolerance_improvement_via_oxide-metal_coatings/12998720 CC BY 4.0 |
