Abstract
SUMMARYScent stimulation is widely used in day lives such as in aromatherapy. However, the effect of scent stimulation on humans remains unclear. Therefore, it is necessary to develop a system to evaluate the cardiovascular response to scent stimulation for use in biofeedback applications. In this study, we developed a device for quantitative and short‐term stimulation. We evaluated the heartbeat response to scent stimulation with this device. The experiments revealed that the R–R interval (RRI) was reduced by grapefruit scent stimulation. In addition, the RRI was likely to be controlled by scent stimulation with grapefruit and lavender.
