Wearable devices, wearable device forming methods, and methods of reuse of transmitter units of wearable devices in continuous analyte monitoring systems

A wearable device configured for use during continuous analyte monitoring, comprising:

• a disposable base unit that includes a sensor assembly and a power source;
• and
• a reusable transmitter unit configured to interface with the disposable base unit and receive power from the power source of the disposable base unit;
• wherein the disposable base unit is configured to be disposed of after a single analyte monitoring period, and
• wherein the reusable transmitter unit is configured to be detached from the disposable base unit after the single analyte monitoring period and re-used with another disposable base unit.

A wearable device for continuous analyte monitoring, comprising:

• a disposable base unit that includes a power source and an analyte sensor;
• and
• a reusable transmitter unit that includes electronic circuitry configured to bias the analyte sensor, measure current through the analyte sensor, and compute analyte values based on measured current through the analyte sensor;
• wherein the disposable base unit is configured to couple to the reusable transmitter unit and supply electrical power to the electronic circuitry of the reusable transmitter unit.
