Breath-based diagnostic device including an array of multiple sensors

摘要

A breath-based diagnostic device. The device includes an array of multiple gas sensors, a database storage device and a microprocessor. The gas sensors contain material capable of reacting with volatile organic chemicals in the exhaled breath of the subject. The database storage device stores established responses to a variety of disease. The microprocessor compares the response detected by the gas sensors and the database so as to perform the diagnosis.
