Abstract
A method of forming a color-changing fiber that can be incorporated into fabrics and other woven materials. The color changing fibers include an annular wall and a conductive wire axially extending through the annular wall, a core strand surrounded by the annular wall and extending axially through a central portion of the fiber, and an encapsulated electro-optic medium disposed on a surface of the core strand.
Claims4
A flexible color-changing fiber comprising:
- an annular wall and a plurality of conductive wires axially extending through the annular wall;
- a conductive core strand surrounded by the annular wall and extending axially through a central portion of the fiber;
- capsules including an electrophoretic medium disposed on a surface of the conductive core strand;
- and
- a layer of semi-conductive material between the conductive core strand and the capsules including an electrophoretic medium, the layer of semi-conductive material allowing electrical driving signals across the full circumferential area of the electrophoretic medium between the conductive core strand and the conductive wires when a voltage is provided between the conductive core strand and the conductive wires.
