Ammonia is an essential chemical for several global industries including agriculture, pharmaceuticals, food processing, energy storage, and medicine. Together these industries generate over 175 million tons of ammonia per year. Despite its widespread use ammonia is highly toxic and damaging to human health and the environment. Effective sensors are essential for ensuring occupational health and safety when handling ammonia gas. These sensors must detect low levels of ammonia quickly and selectively, especially in environments containing other gases. Designing sensors capable of operating at room temperature and high humidity is a major challenge. Though many sensing technologies exist they often require high operating temperatures (up to 400 °C), do not respond quickly, or are not sensitive or selective for ammonia at room temperature. This project will create ammonia sensors that combine rapid response with high selectivity and the ability function over a wide range of humidity conditions at room temperature. This will have a direct impact on the Canadian economy by developing widely sought after sensors for use across multiple global industries. Canadians and Canadian companies will benefit from this technology as it will help safely expand the use of ammonia. Innovations in sensor development will simultaneously address the demands of industry and limit the negative impacts of ammonia on human health and the environment.

氨是几个全球性行业的基本化学品，包括农业，制药，食品加工，能源储存和医药。这些行业每年生产超过1.75亿吨氨。尽管其广泛使用，但氨具有高度毒性，对人类健康和环境具有破坏性。有效的传感器对于确保处理氨气时的职业健康和安全至关重要。这些传感器必须快速、有选择地检测低水平的氨，特别是在含有其他气体的环境中。设计能够在室温和高湿度下工作的传感器是一项重大挑战。虽然存在许多传感技术，但它们通常需要高工作温度（高达400 °C），响应不快，或者在室温下对氨不敏感或不具有选择性。该项目将创建氨传感器，结合联合收割机快速响应与高选择性和能力的功能在广泛的湿度条件下，在室温下。这将对加拿大经济产生直接影响，因为它将开发出广受欢迎的传感器，供全球多个行业使用。加拿大人和加拿大公司将受益于这项技术，因为它将有助于安全地扩大氨的使用。传感器开发的创新将同时满足工业需求，并限制氨对人类健康和环境的负面影响。
