Techniques for temperature measurement according to a calibrated temperature

A wearable ring device comprising:

• one or more processors;
• one or more memories coupled with the one or more processors;
• a plurality of temperature sensors coupled with the one or more processors and the one or more memories, the plurality of temperature sensors comprising at least:
• a primary temperature sensor positioned relative to a first location of a tissue of a user;
• and
• a plurality of secondary temperature sensors each located relative to a respective second location of the tissue of the user;
• and
• instructions stored in the one or more memories and executable by the one or more processors to cause the wearable ring device to:
• acquire first skin temperature data from the first location of the tissue of the user via the primary temperature sensor and second skin temperature data from respective second locations of the tissue of the user via the plurality of secondary temperature sensors;
• calibrate the plurality of secondary temperature sensors using the primary temperature sensor, the first skin temperature data, and the second skin temperature data, wherein calibration of the plurality of secondary temperature sensors comprises adjusting a respective measurement parameter for acquisition of skin temperature data using each secondary temperature sensor of the plurality of secondary temperature sensors;
• acquire additional skin temperature data from the user via at least the plurality of secondary temperature sensors in accordance with the adjusted measurement parameters based at least in part on calibrating the plurality of secondary temperature sensors;
• determine one or more health-related metrics of the user based at least in part on the additional skin temperature data;
• and
• display, via a graphical user interface of a user device associated with the wearable ring device, an indication of the one or more health-related metrics of the user.
