Abstract: According to an embodiment of the present disclosure, a wearable electronic device may comprise: a housing; and a substrate arranged in an inner space of the housing. According to an embodiment, the wearable electronic device may comprise at least one light emitting unit arranged on the substrate. According to an embodiment, the wearable electronic device may include at least one light guide member arranged adjacent to each of the at least one light emitting unit when the wearable electronic device is viewed from one side. According to an embodiment, the wearable electronic device may comprise at least one light scattering member arranged such that light emitted through the at least one light emitting unit and reflected by the at least one light guide member is transmitted to the outside. In addition to various embodiments disclosed in the present document, various other embodiments are possible.

Abstract: A wearable device is provided. The wearable device includes a first ring including a first housing including a first magnet, and a first sensor in the first housing, and a second ring including a second housing including a second magnet, and a second sensor in the second housing, the second ring being detachably coupled with the first ring by magnetic force between the first magnet and the second magnet, wherein the first sensor includes a light-emitting portion configured to emit light toward a portion of a body of a user on which the wearable device is worn, and wherein the second sensor includes a light receiving portion configured to receive, via the second housing coupled to the first housing, at least a portion of the light being emitted from the light emitting portion and passing through the portion of the body of the user.

Abstract: A wearable device is provided. The wearable device includes a temperature sensor arranged to face skin of a user when the wearable device is worn on the user, memory, comprising one or more storage media, storing instructions, and at least one processor communicatively coupled to the temperature sensor and the memory, wherein the instructions are configured, when executed individually or collectively by the at least one processor, to cause the wearable device to identify that the wearable device is worn by the user, and in response to identifying that the wearable device is worn by the user, identify one wearing state corresponding to temperature data among a plurality of wearing states, the temperature data indicating a temperature value measured through the temperature sensor.

Abstract: According to an embodiment, an electronic device includes: a photoplethysmography (PPG) sensor, a temperature sensor, a memory, and a processor. The processor is configured to store first information on blood flow of a user, as associated with second information on temperature of a part of the user's body. The processor is configured to change a state of the temperature sensor from active state to inactive state. The processor is configured to identify that a first value representing the blood flow of the user is out of a first range. The processor is configured to change the state of the temperature sensor from the inactive state to the active state. The processor is configured to, based on identifying that a second value representing the temperature of the part of the user's body is out of the second range, provide a notification.
