1. A wearable sensor for sensing analytes, the wearable sensor comprising:
an analyte microsensor including a plurality of microneedles configured to detect at least one analyte in interstitial fluid in skin of a user, wherein at least one individual microneedle in the plurality of microneedles includes:
a distal region;
an active region isolated to the distal region, the active region including a sensing material operable to generate analyte signals upon detection of the at least one analyte and a conductive material isolated to the distal region; and
an insulating material exposing at least a portion of the active region at the distal region of the individual microneedle.
