Olfactory display using a miniaturized pump and a SAW atomizer for presenting low-volatile scents

Recently, the research on olfactory display for incorporating the sense of smell into virtual reality has gradually expanded. To present odors with a vivid sense of smell, an ability to generate a variety of odors with efficient speed is indispensible. In this paper, we developed a new type of olfactory display, composed of a miniaturized electroosmotic pump and a surface acoustic wave device for presenting the low-volatile scents that are conventionally difficult to be generated with acceptable speed. We used an odor sensing system to evaluate the capability to present the low volatile scent and the ability to blend smells of our proposed new type olfactory display.
