  • Publication number: 20050038368
    Abstract: The invention concerns an intermediate layer (2) for enhancing comfort of a user wearing usual objects on or in the body. The intermediate layer comprises at least an element consisting of a heat-sensitive gel having a lower critical solution temperature (LCST). Under the influence of the user's body or skin temperature (T), the intermediate layer actively produces a constant modification of the contact point(s) between the usual object and the user's body (3).
