1. An analyte sensor system comprising:
an implantable analyte sensor configured to be inserted into a host and continuously monitor at least one analyte;
an adhesive pad configured to be at least partially in contact with a skin surface of the host;
a heating element included in the adhesive pad and positioned to provide heat to the skin surface of the host when the implantable analyte sensor is inserted into the host; and
sensor electronics hardware, wherein the sensor electronics hardware is configured to perform operations comprising:
detecting, by the sensor electronics hardware, that the implantable analyte sensor has been inserted into the host based at least on receiving a signal indicating a change in an electrical property of the implantable analyte sensor;
responsive to receiving the signal indicating the change in the electrical property of the implantable analyte sensor, triggering, by the sensor electronics hardware, power to be provided to the heating element, thereby providing heat to the skin surface of the host upon detection that the implantable analyte sensor has been inserted into the host, wherein the providing of the power to the heating element occurs while the implantable analyte sensor is inserted into the host;
responsive to determining that a relationship between a response signal generated by the implantable analyte sensor and a corresponding concentration of the at least one analyte is non-linear, continuing to provide power to the heating element; and
responsive to determining that the relationship is linear after previously determining that the response signal is non-linear, ceasing to provide power to the heating element.
