The digital scent technology market in North America is estimated to account for largest share during the forecast period.

Increase in healthcare expenditure in North America has propelled the importance on enhancing patient care, diagnosis, and treatment processes. The integration of digital scent technology and e-noses can offer innovative solutions, particularly in healthcare facilities. The substantial increase in Medicare and Medicaid spending further underscores the government's commitment to healthcare, providing opportunities for technology adoption. Bio-sensing is one of the applications that is being used extensively in the healthcare industry. Biosensors are mainly used in the healthcare industry to recognize and track the physiological processes inside the body. It is used for the critical secondary and tertiary analysis of the physiological mechanisms.

The digital scent technology market for e-nose segment to hold largest market share during the forecast period.

Electronic noses (e-noses) emulate the human sense of smell using various sensor technologies and have applications in the medical and defense sectors. In the medical sector, they promise rapid, non-destructive disease diagnosis by analyzing breath, urine, or blood samples, enhancing treatment monitoring, and enabling personalized medicine. 

Medical segment in application to the highest market share of the digital scent technology market during the forecast period

Digital scent technology is used in the medical segment for clinical diagnosis. Human odor as a result from internal hormonal or metabolic changes, contains a biomarker for various diseases and indicates the physiological status of an individual. The main sources of human odor are saliva, sweat, breath, urine, and skin. Recently, the components of skin emissions, exhaled breath, and urine odor have created attention as diagnostic biomarkers of diseases and disorders, including liver disease, lung cancer, diabetes, asthma, cystic fibrosis, and chronic obstructive pulmonary disease. Volatile organic compounds are the major target for e-noses in medical diagnosis, such as ammonia in individuals with liver disease, acetone for patients with diabetes, and alkanes in patients with lung cancer, pentane in patients with asthma. The e-nose technology has the potential to be operated for diagnosis.
