| Outline of Final Research Achievements |
We succeeded in generating a narrow, straight and steerable airflow that is accompanied with ultrasound Bessel beam emitted from a phased array of ultrasound transducers. The cross-sectional area of the flow was observed to be almost comparable to several times of the ultrasound wavelength. Based on this technique, we achieved remote fragrance presentation to a specific user in a personalized fashion, where the scent was transported from the scent source to the user’s nostril via the ultrasound-driven airflows. We also demonstrated that selective transportation of a specific kind of scent out of several sources located close to one another was also possible by our technique. We created a system that offered face-tracking scent that targeted freely moving users wearing no devices.
