description The application of sensitive gas sensors manufactured in high volume at low cost has great interest due to an extensive array of potential applications.

This work reports a straightforward and versatile technique using screen-printing and drop-casting processes, to produce gas sensors on a flexible plastic substrate, based on a combination of metal organic framework and graphene-carbon materials. We demonstrate a sensitive and stable ammonia sensor (4.6% maximal response) over a range from 20 to 100 ppm. The optimized formulation is 36 times higher than a carbon-graphene only sensor and makes the developed devices suitable for intelligent packaging. The sensors production process is fast, reliable and low-cost and so there is a strong potential for the process principles to be adapted industrially for a different gas target or application.
