1. A sensor for sensing analytes present in a body fluid of a user, the sensor comprising:

  • a substrate; and

    a filament including;

    a substrate core including;

    a base end coupled to the substrate,a columnar protrusion having a proximal portion coupled to the base end and a distal portion, anda tip region coupled to the distal portion of the columnar protrusion and configured to provide access to the body fluid of the user;

    a conductive layer, isolated to the tip region of the substrate core and away from the base end as an active region that enables transmission of electronic signals generated upon detection of an analyte within the body fluid;

    an insulating layer surrounding the substrate core and exposing a portion of the conductive layer, thereby defining a boundary of the active region; and

    a sensing layer, in communication with the active region, configured for at least one of amperometric sensing and potentiometric sensing of the analyte.
