Abstract:
1. A stimuli-sensitive composite fiber capable of undergoing a radial mechanical change, with its cross-sectional area comprising: a first material at a core of the fiber, the first material capable of undergoing a physicochemical change in response to an external stimulus, the first material at a core of the fiber having arms of substantially equal length extending outwards from the core, each arm progressively widening as the arm extends from the core; and a second material with a leg adjacent to both sides of each arm of the first material contacting and mechanically engaging each arm of the first material at at least one point, the legs of the second material being forced closer together when the arms of the first material expand, the second material further comprising protrusions that change in position in mechanical response to movements of the legs of the second material.
