1. A wearable continuous analyte monitoring (CAM) system, comprising:
a CAM device comprising:
a transmitter unit comprising an enclosure and wireless transmitter circuitry completely sealed within the enclosure, wherein the wireless transmitter circuitry is operative to receive and wirelessly transmit electrical signals indicative of an analyte level, and the transmitter unit has no power source therein and has electrical contacts on the enclosure for receiving power and the electrical signals;
a sensor unit comprising a power source and a sensor, the sensor extending through the sensor unit and configured to be inserted into skin of a user, wherein the sensor unit has a closable opening for receiving the transmitter unit there through, the sensor unit configured to generate the electrical signals indicative of the analyte level and to electrically connect to the electrical contacts of the transmitter unit in response to receiving the transmitter unit through the closable opening,
wherein the sensor unit is disposable, and the transmitter unit is removable from the sensor unit through the closable opening and is reusable in another sensor unit; and
a CAM cover comprising a fabric covering the sensor unit; and
an applicator comprising:
a main body configured to receive the CAM device therein;
a safety cover positioned over the sensor of the sensor unit received in the main body; and
a rigid skirt attachable to the main body with the CAM device received in the main body, the rigid skirt comprising:
a lid coupled thereto, the lid and the safety cover removable together after the rigid skirt is attached to the main body with the CAM device received in the main body.
