Cannabix Thc Breath Analyzer (Thcba) The THC Breath Analyzer (THCBA),is a point of care breath testing tool for the rapid detection of recent cannabis use (within 1-3 hours). The underlying technology for the THCBA uses microfluidic sensors coupled with machine learning algorithms which operates under principles similar to mammalian olfaction systems. Microfluidic-based artificial olfaction technology pairs gas sensors, such as metal oxide semiconductor, with microfluidic channels for detection of THC in breath samples. The THCBA collects a single breath from the user and the sensor response is represented by a characteristic pattern or “smell-print” to the specific target gas.
