Abstract

An analyte sensor is provided that comprises a substrate which includes a semiconductor material. Embodiments may include a core of a conductive material, and a cladding of a semiconductor material, in which the cladding may form at least a portion of a conducting path for a working electrode of the analyte sensor. Method of manufacturing and using the analyte sensor are described, as are numerous other aspects.

Claims

1. An analyte sensor, comprising:

a substrate including;

a core comprised of conductive material; and

a cladding comprised of semiconductor material, the cladding forming at least a portion of a conducting path for a working electrode wherein the cladding has a tensile strength of at least 1000 MPa.

2. An analyte sensor, comprising:

a substrate including semiconductor material; and

an active region positioned on the substrate and adapted to be exposed to a fluid environment, the active region including an agent adapted to convert an analyte within the fluid environment into a product from which an electrical current may be generated.

3. A method of manufacturing an analyte sensor, comprising:

providing a substrate including semiconductor material; and

applying an electrochemically-active layer on at least a portion of the substrate.

4. The method of claim 3, wherein the electrochemically-active layer is applied on top of the semiconductor material.

5. A method of using an analyte sensor, comprising:

providing an analyte sensor having a substrate including semiconductor material; and

inserting at least a portion of the analyte sensor into a user'"'"'s body.

6. The method of claim 5 wherein the analyte sensor is at least partially inserted into the user'"'"'s body without the use of a trocar.
