High Sensitive Sensors Boost Real-Time Emissions Monitoring
Monitoring of Vehicular Emissions - Highly Selective and Sensitive Chemiresistive Gas Sensors
Tags: IIT Hyderabad, India, Industrial Automation & Manufacturing, Energy & Environment
Researchers have developed chemiresistive gas sensors using advanced materials such as cadmium sulfide and high-entropy oxides for monitoring vehicular emissions and greenhouse gases like CO, NO₂, CO₂, and CH₄. These sensors exhibit high sensitivity, selectivity, and fast response times while being cost-effective and portable compared to traditional methods like gas chromatography. Applications include real-time air quality monitoring, enabling better control of pollution and improved public health outcomes. The innovation leverages ohmic and Schottky contacts in the sensors to enhance gas-specific detection performance. This technology is poised to replace expensive and complex conventional systems, making gas monitoring more accessible and efficient.
