Abstract
This work introduces a groundbreaking Open-Ended Hollow Coaxial Cable Resonator (OE-HCCR) CO2 sensor and the OE-HCCR as a chemical sensing platform technology. This OE-HCCR chemical sensing platform has a displacement detection limit of 0.01nm, interpreted as less than one ppb change in sensing material permittivity values. The OE-HCCR sensor is employed for high-performance CO2 monitoring by integrating novel CO2-sensitive composite materials with the developed platform, marking the first instance of this application worldwide. This sensor has the potential to revolutionize CO2 monitoring in challenging industrial environments, which would contribute to global decarbonization efforts and assist with environmental preservation activities.
