Jones Packaging Inc. (Jones) is an innovative Canadian company dedicated to providing customer-first**integrated packaging solutions. Jones has been actively developing printed electronics based smart packaging**solutions. Currently Jones is looking for various gas sensing analyzers, in particular for those food products**that are sensitive to the storing conditions, which have the potential to threat human health if corrupted.**For food packing industry, the condition of food may vary attribute to different storing conditions, thus the**fixed "expiring date" printed on the package sometimes cannot guarantee the safety of the products. Food**poisoning is the illness resulting from consumption of corrupted food that is either expired or contaminated by**pathogenic bacteria, viruses and/or parasites. Spoiled food will create detectable vapors or gas like ammonia,**which can be detected using gas sensors. However, due to the relative high cost of such gas sensor and the lack**of integration to the packaging, customers cannot benefit from the state-of-the-art dynamic vapor monitoring**systems. Thus, it is urgent to take advantage of the recent advances in materials sciences and printed electronics**technology to develop low-cost all-printed flexible gas sensor.**The objective of this project is to develop printable polymer-based ammonia sensing materials to be used in**a chemiresistor device. Such ink will be used for printing and functioning as the ammonia sensing component.**Together with inkjet printing technology, a high-performance sensing circuit will be developed on a flexible**substrate, like paper.**Printed electronics is emerging as an advanced manufacturing technology in electronics industry.**Development of new functional ink formula for smart packaging can be beneficial for not only the industrial**partner, but also the whole printed electronics industry in Canada.
