WEARABLE ELECTRONIC DEVICE AND OPERATING METHOD THEREFOR

According to various examples of the present invention, a wearable electronic device comprises: an energy harvester for generating electric energy on the basis of a movement or a change in the shape of the wearable electronic device; a first processor for controlling the energy harvester; a first sensor and a second sensor; and a second processor for controlling the first sensor and the second sensor, wherein the first processor transmits, to the second processor, a control signal for transitioning the second processor into an activated state if the electric energy generated by the energy harvester satisfies a designated first condition, and the second processor can be set such that first sensor data is acquired through the first sensor and second sensor data is selectively acquired from the second sensor according to whether the first sensor data satisfies a designated second condition, when the second processor is transitioned from an inactivated state to the activated state by responding to the control signal.
