First Claim
1. A body-mountable device comprising:
- a flexible substrate having a first side and a second side opposite the first side, wherein the flexible substrate is mountable to a skin surface, and wherein the flexible substrate is shaped to have an elongate extension having a distal end configured to extend beneath the skin surface to contact interstitial fluid;
an adhesive layer disposed on the first side of the flexible substrate, wherein the adhesive layer is configured to adhere the flexible substrate to the skin surface;
a sensor, wherein the sensor is disposed at the distal end of the elongate extension, and wherein the sensor is configured to detect an analyte in the interstitial fluid;
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, wherein at least one of the one or more electronic components is disposed on the first side of the flexible substrate; and
a battery, wherein the battery is disposed on the flexible substrate.

Abstract
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.
