It is widely believed that measurement of molecules in exhaled breath can provide a window into the metabolic state of the human body, detect the presence of cancer, monitor respiratory diseases, assess liver and kidney function, determine exposure to toxins, and possibly, even diagnose schizophrenia. Such conjectures are further supported by recent work performed by researchers at the Pine Street Foundation. Laser spectroscopic techniques, in particular, tunable laser absorption spectroscopy (TLAS), are candidate technologies for breath analysis applications. The paper presents the Breathmeter from Ekips Technologies. The Breathmeter is based on TLAS and consists of four primary components: 1) the laser source module, 2) sample gas cell, 3) optical detector, and 4) associated electronics hardware and software. The optical board layout of the breath meter system was shown. Its applications and future works were also discussed
