1. A system comprising:
- a flexible substrate configured to be mounted to a skin surface;
a sensor probe having a first end attached to the flexible substrate and a second end configured to extend beneath the skin surface to contact interstitial fluid;
a sensor configured to measure a physiological property, wherein the sensor is disposed at the second end of the sensor probe, and wherein the physiological property is related to glucose in the interstitial fluid;
a controller; and
a near field communication (NFC) device mounted to the flexible substrate and electrically coupled to the sensor, wherein the NFC device is configured to receive from the sensor one or more sensor measurements indicative of the physiological property, and wherein the NFC device is configured to detect the controller and provide information related to the one or more sensor measurements to the controller in response to detecting the controller,wherein the controller is configured to;
(i) receive the information related to the one or more sensor measurements from the NFC device, (ii) determine a glucose concentration based on the information, (iii) obtain a target glucose concentration, (iv) compare the glucose concentration to the target glucose concentration, and (v) based on the comparing, provide instructions to an insulin delivery device to control an insulin delivery rate to a blood stream by the insulin delivery device.

Abstract
An example system includes a flexible substrate configured to be mounted to a skin surface. The system includes a sensor probe that has a first end attached to the flexible substrate and a second end configured to extend beneath the skin surface to contact interstitial fluid. A sensor is configured to measure a physiological property and is disposed at the second end of the sensor probe. A transmitter is attached to the flexible substrate and is configured to provide information related to sensor measurements to a controller. The controller is configured to a drug delivery rate based on the information.
