SYSTEM FOR MONITORING BODY CHEMISTRY
First Claim
13. A method for monitoring body chemistry of a user, the method comprising:
- providing a first housing portion supporting a microsensor operable to sense an analyte within interstitial fluid of the user, the first housing portion comprising a) an opening into an electrical interface with the microsensor, and b) an adhesive region, surrounding the microsensor at a second surface opposing the electrical interface;
receiving a second housing portion into the opening of the first housing portion, the second housing portion supporting an electronics subsystem configured to contact the electrical interface and receive a signal stream from the microsensor;
with an applicator, accelerating the second housing portion and the first housing portion toward skin of the user, thereby expelling the first and the second housing portions from the applicator, establishing electrical communication between the electronics subsystem and the electrical interface, delivering the microsensor into interstitial fluid of the user, and coupling the adhesive region of the first housing portion to the user.

Abstract
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.
