Abstract
Flexible electronically functional fibers are described that allow for the placement of electronic functionality in traditional fabrics. The fibers can be interwoven with natural fibers to produce electrically functional fabrics and devices that can retain their original appearance.
Claims32
A flexible electrically functional fiber comprising:
- a core portion;
- a first conductive layer surrounding the core portion;
- a dielectric layer surrounding and in direct contact with the first conductive layer;
- a functional layer also surrounding and in direct contact with the first conductive layer and abutted to the dielectric layer, such that the dielectric layer and the functional layer occupy different locations along a longitudinal length of the fiber;
- a second conductive layer surrounding the dielectric layer and the functional layer;
- and
- an insulative layer surrounding the second conductive layer.
4 more elements
An electrically functional fiber comprising:
- a fiber core portion;
- and
- a plurality of layers surrounding the fiber core portion in a concentric arrangement, the plurality comprising:
- a first conductive layer surrounding the fiber core portion;
- a dielectric layer surrounding a first region of the first conductive layer along a length of the fiber;
- a functional layer surrounding a second region of the first conductive layer along the length of the fiber, such that the dielectric layer and the functional layer occupy different locations along the length of the fiber and abut one another, wherein the functional layer comprises at least one of a dielectric material, a piezoelectric material, and a piezoluminescent material;
- a second conductive layer surrounding the dielectric layer and the functional layer;
- and
- an insulative layer surrounding the second conductive layer;
- wherein:
- the functional fiber has an average diameter of less than 5 um;
- and
- at least one layer of the plurality is less than 1 μm in thickness.
