Abstract

In this paper, we report the most sensitive inkjet printed reduced graphene oxide based ammonia sensor as well as the first inkjet printed carbon nanotube based dimethyl methylphosphonate (DMMP) vapor sensor to date. The processes utilized to fabricate the sensors, including substrate surface modification, inclusion of porosity enhancing nanospheres and chemical functionalization, are outlined. The testing set-up and protocols are described and finally the measurement results are shown with displayed sensitivities of 8.5% for 30 ppm of ammonia and 5% for 2.5 ppm of DMMP. These results may set the foundation for fully inkjet printed, conformal, 'zero-power' and low cost ubiquitous wireless multi-gas motes.
