There remains a strong need for miniaturized, low-power gas sensors that can be deployed in wireless applications for improved environmental protection, for public health, and for safe and efficient operation of many industrial processes.
Leveraging the microfabrication technologies and utilizing innovations in high surface area nanomaterials are providing exciting opportunities towards low-power microchemical sensors.
In this presentation, I will discuss recent advances in this area, and present one of our approaches, which is based on a highly efficient microheater platform with fast response and recovery times. By integrating a number of nanomaterials (such as aerogels based on two-dimensional materials) with the sensing platform, we have achieved fast and sensitive detection of several health and environmental pollutants. The talk will end with current limitations and plans for future directions.
Roya Maboudian did her PhD at CalTech and postdoc at IBM. She received several early career awards from PECASE, DOE, NSF, etc. and is currently editor of the IEEE MEMS Journal and co-director of BSAC.
