Performance analysis of SAW gas sensor based on ST-Cut quartz for breath analysis

Performance analysis of SAW gas sensor based on ST-Cut quartz for breath analysis

Abstract- Breath analysis is the recent technique used to detect diseases. Among the advantages of breath analysis are high sensitivity and fast detection. Surface acoustic wave (SAW) gas sensor is one of the sensors that can be used to analyze breath analysis. This work reports on the design an...
