Abstract: A wearable electronic device which can detect a wearing state, comprising: at least one first electrode, provided in a first region of the wearable electronic device; at least one second electrode, provided in a second region of the wearable electronic device; a capacitance calculating circuit, configured to calculate first capacitances generated by the first electrode and configured to calculate second capacitances generated by the second electrode, wherein the capacitance calculating circuit further calculates a capacitance difference between the first capacitance and the second capacitance; and a processing circuit, configured to determine the wearing state according to the capacitance difference. Via such structure, a wearing state, a wearing location, a wearing angle of the electronic device can be automatically detected, thus the problem caused by an improper wearing manner can be improved.
