Abstract :
We spectroscopically investigate the impact of alcohol on blood-pulse waveform and confirm that alcohol intake can be discerned by various sensors. This paper focuses on specific spectra and demonstrates the importance of observing the harmonics ratio of the blood-pulse waveform. An analysis of the temporal evolution of the harmonic ratio shows that it includes important information that allows the intake of alcohol to be discerned.
