Patent number: 11719660Abstract: A solid state, carbon dioxide (CO2) sensor configured for sensitive detection of CO2 in both dry and moist conditions. The CO2 sensor utilizes a composite sensing material that detects CO2 in the range of 100 ppm to 10,000 ppm. The sensing material is composed of O-MWCNTs and a metal oxide functionalizing agent, such as iron oxide (Fe2O3) nanoparticles. The material has an inherent resistance and conductivity that is chemically modulated as the level of CO2 increases. The CO2 gas molecules that are absorbed into the carbon nanotube composites cause charge-transfer and changes in the conductive pathway causes changes in conductivity of the composite sensing material. This change in conductivity provides a specificity and sensitivity for CO2 detection. The CO2 sensor can be easily integrated into existing electronic circuitry and hardware configurations, including the hardware of a mobile computing device, such as a smart phone or tablet device.Type: GrantFiled: July 9, 2020Date of Patent: August 8, 2023Assignee: United States of America as Represented by the Administrator of NASAInventors: Jing Li, Ami Milan Hannon
