Abstract

Pre-connected analyte sensors are provided. A pre-connected analyte sensor includes a sensor carrier attached to an analyte sensor. The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.

First claim

What is claimed is:

1 . An apparatus, comprising:
an analyte sensor comprising:
an elongated body;
a first electrode in electrical communication with a first conductive contact, and
a second electrode in electrical communication with a second conductive contact; and
a sensor carrier attached to the analyte sensor, the sensor carrier including an intermediate body,
a first conductive portion disposed on the intermediate body, the first conductive portion in electrical communication with the first conductive contact,
a second conductive portion disposed on the intermediate body, the second conductive portion in electrical communication with the second conductive contact,
wherein the first and second conductive portions form a connection portion configured to establish electrical communication between the first and second conductive contacts and a separate device.

2 . The apparatus of claim 1 , further comprising:
an identifier coupled to the intermediate body.

3 . The apparatus of claim 2 , wherein the identifier, the sensor, and the intermediate body form a laminated configuration.

4 . The apparatus of claim 2 , wherein the identifier is a QR code sheet.

5 . The apparatus of claim 2 , wherein the identifier is any of an optical identifier, a radio-frequency identifier, or a memory-encoded identifier.

6 . The apparatus of claim 5 , wherein the identifier is configured to identify any of the analyte sensor, calibration data for the analyte sensor, and a history of the analyte sensor.

7 . The apparatus of claim 1 , wherein the first conductive portion and the second conductive portion are traces.

8 . The apparatus of claim 7 , wherein the traces form exposed contact surfaces in the connection portion.

9 . The apparatus of claim 1 , wherein the first and second conductive portions are at least partially embedded in the intermediate body.

10 . The apparatus of claim 1 , wherein the first conductive portion and the second conductive portion include at least one of a solder weld, a conductive tape, a coil spring, a leaf spring, or a conductive elastomer.

11 . The apparatus of claim 1 , wherein the connection portion is configured to mechanically mate with the separate device.

12 . The apparatus of claim 1 , wherein the separate device is an electronics unit configured to measure analyte data.

13 . The apparatus of claim 1 , wherein the separate device is a component of a manufacturing station.

14 . The apparatus of claim 13 , wherein the manufacturing station is configured to perform at least one of a potentiostat measurement, a dipping process, a curing process, a calibration process, or a sensitivity measurement.

15 . The apparatus of claim 13 , wherein the manufacturing station comprises a calibration station configured to de-establish electrical connection between the sensor and the calibration station and establish electrical connection between the sensor and at least one testing station via the connection portion of the sensor carrier.

16 . The apparatus of claim 1 , wherein the intermediate body further comprises a datum structure configured to control a position and spatial orientation of the analyte sensor relative to a substrate of the intermediate body.

17 . The apparatus of claim 1 , wherein the first electrode is positioned coaxially within the second electrode.

18 . The apparatus of claim 17 , wherein the first electrical contact and the second electrical contact are longitudinally aligned and spaced along a longitudinal axis of the sensor.

19 . The apparatus of claim 1 , wherein the first electrode and the second electrode are affixed to a flexible planar substrate.

20 . The apparatus of claim 19 , wherein the first conductive contact and the second conductive contact are affixed to the flexible planar substrate.

21 . The apparatus of claim 1 , wherein the first conductive contact and the second conductive contact are affixed to the intermediate body with conductive adhesive.

22 . The apparatus of claim 1 , wherein the first conductive contact and the second conductive contact are affixed to the intermediate body with anisotropic conductive film.
