Perovskite-Based Gas Sensors

Emerging trends in metal oxide-based electronic noses for healthcare applications: a review

“…Various types of sensors have met these criteria in different E-nose systems, including optical, electrochemical, catalytic field-effect, surface acoustic wave, conducting polymers, calorimetric, quartz crystal microbalance, and chemiresistive sensors. [26][27][28] Initially, artificial analyte mixtures are used to test the discerning capabilities of sensor arrays before they are used with human breath samples. The unique response patterns to each analyte help establish a relationship between the sensors' sensitivity and selectivity.…”
