Abstract

Different substrates have been explored for their use in printed electronics. Among substrates, paper is an important option for the smart packaging segment. Paper is highly porous and hydroscopic in nature. It undergoes dimensional changes upon exposure to changes in humidity and temperature, which can significantly affect the electrical performance of printed features.

Experiments were performed to extend the findings of previous researchers over a broader range of temperature and humidity conditions, in order to establish a correlation between temperature, humidity and resistance of silver-based inks for printed electronics. The heat cured Gravure printed traces were tested for various relative humidity and temperature conditions to determine the effect on resistance i.e. on performance of conductive ink in different climatic conditions. Substrate properties like Roughness, Porosity and Permeability were also studied to find interaction with the electrical property of the conductive printed traces.
