1. A physiological characteristic sensor device comprising:
a base substrate having an exterior surface and an interior surface opposing the exterior surface;
a conductive circuit pattern formed overlying the interior surface of the base substrate;
a physiological characteristic sensor element located on the exterior surface of the base substrate, the physiological characteristic sensor element comprising sensor electrodes;
conductive plug elements located in vias formed through the base substrate, each conductive plug element having a first end electrically coupled to one of the sensor electrodes, and having a second end electrically coupled to the conductive circuit pattern, the vias and the conductive plug elements being configured to employ a counterbore methodology to provide mechanical support for an insertion needle for deploying the physiological characteristic sensor element in a user;
a multilayer component stack carried on the base substrate and connected to the conductive circuit pattern, the multilayer component stack comprising components to provide processing and wireless communication functionality for sensor data obtained in association with operation of the physiological characteristic sensor device; and
an enclosure structure coupled to the base substrate to enclose the interior surface of the base substrate, the conductive circuit pattern, and the multilayer component stack.
