  • Gas Detection System with Enhanced Selectivity
    Publication number: 20260194503
    Abstract: The present disclosure relates to a gas sensing method with enhanced selectivity. Specifically, the present disclosure relates to a gas sensing method for more accurately distinguishing various types of gases through a process of analyzing a correlation of two or more kinetic or static parameters from a temperature-dependent resistance change of a gas sensor according to two or more temperature conditions by changing the temperature of a captured external gas via a temperature control device.
    Type: Application
    Filed: December 30, 2025
    Publication date: July 9, 2026
    Inventors: Kyu Hyoung LEE, Min Young KIM, Chul Oh PARK, Ha Eun CHOA
  • GAS DETECTION SYSTEM WITH ENHANCED SELECTIVITY
    Publication number: 20260194484
    Abstract: The present disclosure relates to a gas sensing method with enhanced selectivity. Specifically, the present disclosure relates to a gas sensing method for more accurately distinguishing various types of gases through a process of analyzing a correlation of two or more kinetic parameters or static parameters from a resistance change of a gas sensor according to concentration under two or more concentration conditions, by changing a concentration of a captured external gas through dilution or concentration.
