Abstract: A secondary battery comprises an electrode assembly, a can, and an insulator. The electrode assembly includes a first electrode, a separator, and a second electrode alternately stacked and wound. The can has an accommodation part accommodating the electrode assembly therein, and the can comprises a first can and a second can having cylindrical shapes open in a direction facing each other. The insulator insulates an overlapping portion between the first can and the second can. The first can is electrically connected to the first electrode, and the second can is electrically connected to the second electrode. The insulator has a short-circuit induction through-part defined by a through-hole or a cutoff line, such that a short circuit occurs between the first can and the second can through the short-circuit induction through-part when it is deformed in shape as heat or a pressure is applied to contract or expand the insulator.

Abstract: 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 sig
