Abstract

An electrically conductive article that includes a monolithic glass body having a first primary surface; and an electrically conducting element formed in the body. The element includes a discrete layer, or a plurality of discrete layers, of metallic silver. Each layer has a thickness T such that 0.1 μm≤T≤0.5 μm and an electrical resistivity of about 50 nΩ·m to about 2000 nΩ·m. In addition, the element is spaced apart from the first primary surface by a distance D, wherein 0.1 μm≤D≤20 μm. In some aspects, the electrically conducting element and/or the monolithic glass body are configured as an antenna assembly, an optical fiber or a flexible glass substrate.

First claim

What is claimed is:

1. An electrically conductive article, comprising:
a monolithic glass body having a first primary surface; and
an electrically conducting element formed in the body, the element comprising a discrete layer, or a plurality of discrete layers, of metallic silver,
wherein each layer has a thickness T such that 0.1 μm≤T≤0.5 μm and an electrical resistivity (ρ) of about 50 nΩ·m to about 2000 nΩ·m, and
further wherein the element is spaced apart from the first primary surface by a distance D, wherein 0.1 μm≤D≤20 μm article, and
wherein the monolithic glass body is configured as a fiber having a diameter between about 50 μm and about 600 μm.

2. The article of claim 1 , further comprising:
a layer of compressive stress extending into the body having a depth of layer DOL of up to about 60 μm and magnitude of compression CS≥200 MPa.

3. The article of claim 1 , wherein each layer has a thickness T such that 0.1 μm≤T≤0.5 μm and an electrical resistivity of about 100 nΩ·m to about 500 nΩ·m.

4. The article of claim 1 , wherein the conducting element comprises a plurality of discrete layers of metallic silver, each layer spaced apart from an adjacent discrete layer of metallic silver by a spacing S such that S≤500 nm.

5. The article of claim 1 , wherein the diameter is about 150 μm.

6. An electrically conductive article configured as a fiber, comprising:
a first surface;
a fiber core having a central axis;
a glass body that extends from the first surface to the central axis, wherein the glass body has a diameter of between about 50 μm and about 600 μm; and
one or more discrete layers of metallic silver embedded in the glass body beneath the first surface configured to provide an electrical connection along the fiber.

7. The article of claim 6 , wherein the diameter is about 150 μm.

8. The article of claim 6 , wherein the fiber is an optical fiber.
