Abstract: A cover-type electronic device includes a cover-type housing, an electrode set including a plurality of electrodes disposed on an exterior surface of the housing, and a printed circuit board electrically connected to the plurality of electrodes. A driving circuit in the printed circuit board is configured to acquire sensing information, and identify a user's gripping posture, which matches one of a plurality of gripping postures for measurement of designated biometric data, based on the sensing information. The driving circuit identifies information corresponding to a contact impedance difference between both hands of the user from a biosignal detected through the electrode set, and switches a connection state of the electrode set, based on the corresponding information such that the user's biometric data is measured in the switched state.
