Breath Analysis

Dr. Stefan Weigl received his master’s degree in engineering (M. Eng.) from the Ostbayerische Technische Hochschule (OTH) of Regensburg in Germany in 2016. In the course of his master thesis, he started his research on the photoacoustic gas sensing technique in 2015. He received his Doctorate of Natural Sciences (Dr. rer. nat.) in 2021 at the faculty of chemistry and pharmacy of the University of Regensburg. Within his PhD thesis, he investigated the applicability of UV LEDs and IR lasers for the photoacoustical detection of acetone in human breath exhale. Currently, Dr. Stefan Weigl is part of the photoacoustic team of the Sensorik-Applikationszentrum (SappZ), which is located at the Ostbayerische Technische Hochschule (OTH) of Regensburg and supervises the breath analysis research group.

“An excellent contribution to breath analysis not only for analytical chemists but also for anybody interested in novel diagnostic approaches and point-of-care testing concepts … . The compilation of chapters is a great inspiration for analytical scientists and researchers … .” (Sabine Szunerits, Analytical and Bioanalytical Chemistry, Vol. 415 (8), 2023)
