Integrated electrochemical diagnostics for gas sensors

气体传感器广泛用于各种环境，以确保人身安全，包括医疗环境，化学制造工厂和采矿。这些传感器，特别是那些有毒气体需要定期测试，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，其中传感器暴露在目标气体中以确认安全操作。消除这种需求将增加传感器的操作时间并提高安全性。在这个项目中，你将学习先进的电化学方法和气体传感器的电化学和质量传递响应的计算建模。特别强调将放在用于医疗设备的气体传感器。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，将研究成果纳入商业可行的设备中。

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.
