Abstract: Physical implementation of controlled release, as in traditional audiovisual entities, is the prime hindrance in the development of olfactory display. Therefore, attention was focused on the use of functional high-polymers for the controlled release of aromatic fragrances. Among functional high-polymers, temperature sensitive hydrogels were used in an attempt to control the release of aromatic fragrances, because the temperature stimuli for sensitive hydrogels can easily cause a reversible conversion action between sol and gel. Aromatic molecules become active in sol form, and are restrained when they are in gel form. Based on this principle, the measured quantity of aromatic fragrance emission indicated that the emission from gel was more controllable than that from a sol. In addition, sensory evaluation of aroma intensity was performed among individuals using a Peltier-module with embedded olfactory display. Efficiency was evaluated by heating the module to emit the aroma and by cooling the module to stop the emission of aroma. As a result of evaluation, it was verified that hydrogels respond well and are effective for controlled release. Effective timed release was also demonstrated when used in conjunction with video display.
