Microsystem in LTCC Technology to the Detection of Acetone in Exhaled Breath

Artur Rydosz
Abstract— An acetone is a well-known diabetes biomarker, since patients with diabetes tend to have higher acetone levels in their breath than healthy people. Exhaled acetone levels are usually in the range of 0.3-0.9 ppm (parts per million) for healthy subjects and over 3 ppm for patients with diabetes. Commercially-available gas sensors are under development for measuring samples at several tens ppm. Due to this fact, the microsystem with micropreconcentrator and sensor array is proposed as a solution that overcomes these limitations. The microsystem designed by author was manufactured in LTCC (Low Temperature Cofired Ceramics) technology. The microsystem based on micropreconcentrator structure as well as metal oxide gas sensors array. Acetone in diabetic breath was found to be higher than 1.11 ppm, while its concentration in normal breath was lower than 0.83 ppm.

Index Terms— Breath analysis, low temperature cofired ceramics (LTCC), exhaled acetone measurements, micropreconcentrators.
