Flexible and Printable Sensors for Early Detection of Food Spoilage

该项目旨在开发一个技术平台，用于制造柔性传感器，以检测食品腐败和危及生命的微生物污染。通过设计刺激响应墨水，比色，化学电阻和阻抗传感器阵列将被印刷在柔性塑料和纸质基底上。印刷的传感器阵列将通过颜色或电气特性的变化对食品变质和腐败、微生物病原体、温度和pH值产生的气体和挥发性化合物做出响应，从而提供实时测量。该项目将能够沿着供应链设计高效的数据驱动决策工具，以提高食品安全并减少食品浪费。

This project aims to develop a technological platform for the fabrication of flexible sensors that enable the detection of food spoilage and life threatening microbial contamination. By engineering stimuli-responsive inks, colorimetric, chemiresistive, and impedimetric sensor arrays will be printed on flexible plastics and paper substrates. The printed sensor arrays will respond to gases and volatile compounds generated from food deterioration and spoilage, microbial pathogen, temperature and pH by a change in their colour or electrical properties, hence providing real-time measurements. The project will enable to design efficient data-driven decision making tools along the supply chain to enhance food safety and reduce food waste.
