Abstract

This paper will discuss recent advances in state-of-the-art inkjet printing of novel materials for wireless sensing applications. The work includes development of a prototype sensor based on high performance inkjet printed graphene thin films. The thin films were fabricated from direct write of environmentally friendly, water soluble graphene oxide (GO) inks, which were then reduced to obtain the final film. The resulting sensor demonstrates excellent sensitivity compared to existing thin films, along with remarkable recovery time at room temperature without the use of high temperature or UV treatments as reported in literature. In a response to ammonia gas (NH3), we observed a 6% change in normalized resistance after an exposure to 500 ppm of NH3. In addition, over 30% of material restoration is observed within five minutes in ambient conditions.
