Abstract

Resonant sensors are used to detect and measure wave frequency and have many industrial applications that are just beginning to be explored. The Resonant Sensor: DuPont and Smart Surface project is a groundbreaking research project that is headed by Dr. Nigel Reuel, a professor in the Department of Chemical Engineering at Iowa State University. The project also includes a partnership with DuPont and other university faculty members. My work in the spring of 2019 was done as a sub-project of this overarching research venture and involved using these resonant sensors to observe enzyme activity in soil. Being able to use resonant sensors to monitor enzyme activity opens the door to using these sensors in other industrial applications due to their ability to be used cheaply, effectively, and in compact spaces. The presented work analyzed the effects of measuring the resonant signal under differing conditions, such as how far the resonator is buried underground and the amount of water present in the soil. The project also included optimization of the experimental design in order to collect meaningful data and the solving of real-time problems as they came up during the project. The project delivered meaningful results and helped push the research project along as it continues its groundbreaking research.
