The advancements of chemical sensors over the past 50 years have significantly expanded diversity available making them more affordable, portable, sensitive, and partially chemically selective. Despite these advancements, capability used in breath analysis has remained limited due to challenges that persist this field. This encompasses fluctuations humidity, temperature, oxygen concentration within all pose can affect sensor output. review article aims introduce compare techniques current arrays for analysis. A brief overview discrete employed research, at both commercial research levels, is discussed. Furthermore, trends data described. Finally, a detailed outlook recent diagnostic results from studies implementing last 5 outlined.
