Methods, systems, and devices for temperature calibration are described. A device may support temperature calibration for a set of temperature sensors. For example, a wearable device may activate a set of temperature sensors associated with the wearable device. The set of temperature sensors may include a primary temperature sensor and one or more secondary temperature sensors. The wearable device may determine a trigger to calibrate the one or more secondary temperature sensors based on one or more conditions, and calibrate the one or more secondary temperature sensors using the primary temperature sensor based on the trigger. Based on the calibrating, the wearable device may process temperature data associated with a user that is received from one or more of the primary temperature sensor or the one or more secondary temperature sensors.

Techniques for temperature measurement according to a calibrated temperature

Methods of manufacturing and devices for a wearable ring device with a battery in the cover of the device are described. The wearable ring device includes an outer shell component with an inner circumferential surface. The battery may extend radially around at least a portion of a circumference of the wearable ring device. In some cases, the wearable ring device may include a battery chamber configured to enclose the battery and charge carriers. One or more structural boundaries of the battery chamber are formed by a cavity within the inner circumferential surface and a battery cover layer coupled to the inner circumferential surface. The wearable ring device may include a printed circuit board (PCB) including a plurality of sensors electrically coupled to the battery. The PCB overlaps with the battery for at least a portion of the circumference of the wearable ring device.
