Abstract: 本研究では,従来の嗅覚ディスプレイ研究が物理感覚である視聴覚のように物理的な放出制御に依存していることを問題点として取り上げ,化学的な放出制御として機能性高分子に着目し,香料の放出制御を行った.特に,機能性高分子の中でも,温度刺激によりゾル・ゲルの可逆変換作用をする温度敏感性ハイドロゲルを用い香料の放出制御を試みた.分子の運動がゾル状のときに活発化し,ゲル状では抑制されるという原理に基づいて香料放出量の計測を行った結果,ゾル状よりゲル状での放出量が抑制されることを確かめた.また,ペルチェ素子により芳香を提示するときには加熱作用を,芳香を停止するときには冷却作用を行う嗅覚ディスプレイを構築し,人による香り強度の官能評価を行った.評価実験の結果,温度敏感性ハイドロゲルによる放出制御の有用性と,ビデオへの応用における一定の効果を確認した. : 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.
