24 . A wearable patch system, comprising:
a housing;
a sensing system coupled to the housing and including a microsensor and a electronics subsystem, wherein the microsensor has a plurality of microneedles, wherein one or more subsets of microneedles of the plurality of microneedles are configured to generate one or more electrical signals in response to an analyte of interest in interstitial fluid within a user's skin, wherein the electronics subsystem is programmed process the one or more electrical signals received from the microsensor for analyte analysis;
an adhesive substrate including an opening through which the microsensor extends such that the microneedles of the plurality of microneedles are positioned to be inserted within the user's skin, wherein the adhesive substrate surrounds the microsensor and is configured (a) to attach the housing to a surface of the user's skin and (b) to hold analyte-detecting regions located at distal end regions of the microneedles within the user's skin and separated from the surface of the user's skin.
25 . The wearable patch system of claim 24 wherein the adhesive substrate is configured to hold the analyte-detecting regions within the user's skin at a depth less than 350 microns.
26 . The wearable patch system of claim 24 further comprising a non-invasive sensor configured to generate an output indicative of a state of a user.
27 . The wearable patch system of claim 26 wherein the electronics subsystem is further programmed to control, based at least in part on the output generated by the non-invasive sensor, operation of one or more electrodes to compensate for the state of the user.
28 . The wearable patch system of claim 27 wherein:
the one or more electrical signals received from the microsensor are controlled based at least in part on the output generated by the non-invasive sensor; and
the electronics subsystem is programmed to process the one or more electrical signals to generate information related to a parameter indicative of at least one health condition of the user.
29 . The wearable patch system of claim 24 wherein:
the electronics subsystem is further programmed to wirelessly transmit the processed one or more electrical signals or first information based at least in part on the processed one or more electrical signals to a computing device; and
the computing device is configured to (a) further process the processed one or more electrical signals of the first information, (b) display the processed one or more electrical signals, the first information, or second information based at least in part on the processed one or more electrical signals or on the first information, or (c) any combination thereof.
