| Outline of Final Research Achievements |
In this research project, an olfaction aid system that allows the user to sense smells with amplified sensitivities has been developed. In the proposed system, air samples are sucked by using a pump into a flow-through cell that houses an adsorbent. Odor molecules wafting in the air are collected on the surface of the adsorbent. Then, odor vapor with an increased concentration is generated by heating the adsorbent to thermally desorb odor molecules. In the proposed system, a nano-porous silica monolith adsorbent is used because of its large surface area and high adsorption capability. A disk silica monolith adsorbent is directly glued on a heater to attain quick thermal desorption of the collected odor molecules. Experimental results show that odor vapor with four times higher concentration can be presented in 8 s by using the fabricated prototype system. The proposed system is expected to be used for assisting aged people with declined olfaction capabilities.
