SYSTEMS, DEVICES, AND METHODS RELATED TO KETONE SENSORS

Abstract

Systems are provided for an in vivo ketone sensor having a distal portion configured for placement in contact with an interstitial fluid of a user and a proximal portion including a working electrode, a sensing layer with β-hydroxybutyrate dehydrogenase, and a membrane layer configured to limit transport of one or more biomolecules. The in vivo ketone sensor is configured to generate signals at the working electrode corresponding to an amount of ketone in the interstitial fluid. Further, the systems includes a sensor control unit having at least one contact in electrical communication with the proximal portion of the sensor, which is configured to receive the generated signals, and convert the generated signals to ketone concentration data using a sensitivity associated with the in vivo ketone sensor. Also included is a transmitter configured to communicate ketone concentration data to a remote device.
