Embodiment Construction

[0019] In the following detailed description, numerous specific details are set forth by way of example in order to provide a thorough understanding of the relevant teachings. It will be apparent, however, to one skilled in the art that the present teachings may be practiced without such details.

[0020] In general, various embodiments of the invention include a central conductive fiber or wire that has been coated with an electro-optic medium, preferably an electrophoretic medium, and also includes a second conductor applied to the electro-optic medium such that the electro-optic medium layer is located between the central conductive fiber and the outer between conductors.

[0021] The term "electro-optic" as applied to materials, which is used here in its conventional meaning in the field of imaging, refers to materials having first and second display states, at least one of which is The optical properties are different, and the material is changed from its first display s...

Abstract

An electro-optic fiber includes a conductive fiber, a layer of electro-optic medium on the conductive fiber, and a conductor on the layer of electro-optic medium. A method of making the electro-optic fiber including the steps of coating a conductive fiber with an electro-optic medium and applying a conductor to the electro-optic medium. The resulting fibers can be woven to create a color-changing material, such as a fabric.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 739,684, filed October 1, 2018. All patents, published applications and references disclosed herein are hereby incorporated by reference in their entirety. technical field [0003] This invention relates to electro-optical fibers. More specifically, in one aspect, the invention relates to thread-like materials having electrically switchable optical properties, such as color, and methods of making the same. Background technique [0004] Many types of clothing have been developed. This is not only due to the various applications that clothing requires (such as cold weather or sports), but mainly due to satisfying consumers' personal preferences in terms of fashion. For example, if modern fabrics were able to change color as desired, a consumer could significantly reduce the number of clothes he or she would buy in a lifetime. For example, three different shir...
