生体情報計測を用いた増粘多糖類溶液のレオロジー特性が情動に与える影響評価

抄録

In daily life, scenarios of skin contact with liquids have become increasingly diverse, and liquids having various properties are being handled. Therefore, many studies have reported the influence of liquid properties on human sensibility. Many studies have been conducted on the influence of the rheological properties of liquids, which affect tactile sensation during application, using sensory indices based on questionnaires. In this study, the influence of the rheological properties of liquids on the tactile sensibility was investigated in terms of the cerebral blood flow and electrocardiographic bioindicators. The results of the study showed significant differences in the cerebral blood flow depending on the conditions. Furthermore, the results of the correlation analysis between the questionnaire and biological information suggested the possibility of using biological information to evaluate the comfort of liquid applications.
