Integrated electrochemical diagnostics for gas sensors

气体传感器用于各种环境中，以确保人身安全，包括医疗环境，化学制造厂和采矿业。这些传感器，特别是有毒气体传感器，需要定期测试，以确保其安全运行。在这个项目中，学生将成为重新设计电化学气体传感器的团队的一员，以消除所谓的碰撞测试的需要，其中传感器暴露于目标气体以确认安全操作。消除这种需求将增加传感器的操作时间并提高安全性。在该项目中，您将学习先进的电化学方法和气体传感器的电化学和传质响应的计算建模。将特别强调用于医疗器械的气体传感器。该项目提供了一个机会，通过与霍尼韦尔的一个部门城市技术合作，将研究纳入一个商业上可行的设备。

Gas sensors are used in a wide variety of settings to ensure personal safety, including medical environments, chemical manufacturing plants, and in mining. These sensors and in particular those for toxic gases require regular testing to ensure their safe operation. In this project the student will be part of a team that are re-designing electrochemical gas sensors to remove the need for so-called bump testing wherein the sensor is exposed to the target gas to confirm safe operation. Removing this need will increase the operational time for the sensors and improve safety. In the project you will learn both advanced electrochemical methods and computational modelling of the electrochemical and mass transport responses of gas sensors. Particular emphasis will be placed on gas sensors used in medical devices. The project offers the opportunity to see the research incorporated into a commercially viable device through collaboration with City Technology, a division of Honeywell.
