M.Eng. Thesis: Gas Sensing for Cooling and Combustion using Micro-Electro-Mechanical Systems
University of Oxford, Oct 2022 to Jun 2023. Supervised by Professor Kam Chana and Professor John Coull. First-class honours.Developed a novel method of high frequency and high sensitivity gas analysis by pulsing, through a soldered 9-pin d-sub connection, the tungsten filament of a MEMS gas flow sensor as a thin-film and obtaining heat curves. Derived and validated a finite-elements model using high pressure argon gas, compressed dry air and exhaled breath. Improved the measurement frequency by 3 orders of magnitude compared to gas sensors on the current market
