Bandage type of continuous glucose monitoring system

摘要

A flexible, body-mountable analyte sensing device includes a flexible substrate configured for mounting to skin of a living body. The sensing device additionally includes a sensor probe attached to the flexible substrate and configured to penetrate the skin such that a sensor disposed on the sensor probe can detect an analyte in interstitial fluid. The sensor probe can include an elongate extension of the flexible substrate. The sensor can be, for example, an electrochemical sensor or an optical sensor. The sensing device is configured to wirelessly indicate detected concentrations or other information about the analyte in the interstitial fluid. The flexible substrate of the sensing device is configured to be adhered or otherwise mounted to the skin in a manner that minimally impacts activities of the living body.

1. A body-mountable device comprising:
a flexible substrate, wherein the flexible substrate is configured to be mounted to a skin surface; a sensor probe, wherein a first end of the sensor probe is attached to the flexible substrate, and wherein a second end of the sensor probe is configured to extend beneath the skin surface to contact interstitial fluid; a sensor, wherein the sensor is disposed at the second end of the sensor probe, and wherein the sensor is configured to detect an analyte in the interstitial fluid; and one or more electronic components disposed on the flexible substrate, wherein the one or more electronic components are configured to (i) use the sensor to obtain data related to the analyte and (ii) communicate the data related to the analyte to an external device.
