Development of printable ammonia sensors for smart packaging application

琼斯包装公司(琼斯)是一家创新的加拿大公司，致力于提供客户至上的**集成包装解决方案。琼斯一直在积极开发基于印刷电子产品的智能包装**解决方案。目前琼斯正在寻找各种气敏分析仪，特别是对储存条件敏感的食品**，这些产品如果损坏可能会威胁人类健康。**对于食品包装行业，食品的状况可能会因不同的储存条件而有所不同，因此包装上印有**固定“有效期”的**有时不能保证产品的安全。食物中毒是指因食用过期或被**致病细菌、病毒和/或寄生虫污染的腐败食物而引起的疾病。变质的食物会产生可检测到的蒸气或氨等气体，**这些气体可以用气体传感器检测到。然而，由于这种气体传感器的成本相对较高，而且缺乏与包装的**集成，客户无法从最先进的动态蒸汽监测**系统中受益。因此，迫切需要利用材料科学和印刷电子技术的最新进展**来开发低成本的全印刷柔性气体传感器。**本项目的目标是开发用于**化学电阻装置的可印刷聚合物氨气传感材料。这种油墨将用于打印并用作氨气传感元件。**与喷墨打印技术一起，将在柔性**基板上开发高性能的传感电路，如纸张。**印刷电子正在成为电子行业的先进制造技术。**开发用于智能包装的新功能油墨配方不仅对工业**合作伙伴有利，而且对加拿大整个印刷电子行业也是有利的。

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.
