Olfactory display using surface acoustic wave device and micropumps for wearable applications

Abstract

Olfaction is expected to provide reality and a sense of immersion in multimedia contents. Therefore, an olfactory display, a gadget to present scents to one or more user(s), has been developed. A wearable olfactory display has advantage from the viewpoint of reducing the odorant diffusion into the atmosphere and is suitable for virtual reality applications. In this study, we developed a portable olfactory display using surface acoustic wave (SAW) device and micropumps. In the experiment using quartz crystal microbalance (QCM) gas sensor, we confirmed that the olfactory display can present the odorant with intended intensity.
