Towards Objective Olfactory Evaluation Based On Peripheral Arterial Stiffness And Heart Rate Variability Indices

This paper proposes an olfactory stimulation-biological response measurement system aiming for quantitative and objective evaluation the odor quality. The system calculates arterial stiffness index $\beta $ proposed by our group, the low frequency/high frequency (LF/HF), and heart rate (HR) during presenting odor stimuli. An experiment of olfactory sensory assessment using the proposed system is conducted. The experiment results showed that unpleasant odor increases arterial stiffness index $\beta $ and (LF/HF).
