SYSTEM FOR MONITORING BODY CHEMISTRY

摘要

A system and method for monitoring body chemistry of a user, the system comprising: a housing supporting: a microsensor comprising a first and second working electrode, a reference electrode, and a counter electrode, and configured to access interstitial fluid of the user, and an electronics subsystem comprising a signal conditioning module that receives a signal stream, from the microsensor, wherein the electronics subsystem is configured to detect an impedance signal derived from two of the first working electrode, the second working electrode, the reference electrode, and the counter electrode; and a processing subsystem comprising: a first module configured to generate an analysis indicative of an analyte parameter of the user and derived from the signal stream and the impedance signal, and a second module configured to transmit information derived from the analysis to the user, thereby facilitating monitoring of body chemistry of the user.

1. A system for monitoring body chemistry of a user, the system comprising:
a housing comprising a first housing portion coupleable to the user and including an opening, and a second housing portion insertable into the opening of the first housing portion in a first configuration, the first housing portion supporting:
a microsensor comprising a first working electrode, a second working electrode, a reference electrode, and a counter electrode, and configured to access interstitial fluid of the user upon coupling of the housing to the user in the first configuration of the housing, andthe second housing portion supporting: an electronics subsystem comprising a signal conditioning module configured to receive a signal stream, from the microsensor, and configured with a shifted potential different than a reference potential of the reference electrode, wherein the electronics subsystem is configured to detect an impedance signal derived from two of the first working electrode, the second working electrode, the reference electrode, and the counter electrode in response to an applied voltage near the shifted potential; and a processing subsystem in communication with the electronics subsystem and comprising: a first module configured to generate an analysis indicative of an analyte parameter of the user and derived from the signal stream and the impedance signal, and a second module configured to render information derived from the analysis at an electronic device associated with the user, thereby facilitating monitoring of body chemistry of the user.
