1. A wearable device comprising:
a first respiration sensor, configured to sense respiration of a user to obtain a first respiration information; and
a second respiration sensing module, configured to sense respiration of the user to obtain a second respiration information, wherein the second respiration sensing module comprises:
a substrate;
a first electrode, disposed on a first surface of the substrate;
a second electrode, disposed on the first surface of the substrate;
a stretchable conductive element, physically and electrically connected between the first electrode and the second electrode; and
a distance control member configured to control the length of the stretchable conductive element to be greater than or equal to a preset value,
wherein the respiration of the user is judged according to the first respiration information and the second respiration information, and a projection of the first electrode and the second electrode on the substrate does not overlap with a projection of the distance control member on the substrate.
