An electronic device for obtaining biometric information is provided. The electronic device includes at least one communication circuit, a first pad including a first electrode and a second electrode, the first electrode being coated with a catalyst associated with first biometric information, a second pad including at least a third electrode, and a processor for controlling the at least one communication circuit, the first pad, and the second pad. The processor is configured to obtain the first biometric information, based at least on an electric current generated by applying a specified voltage between the first electrode and the second electrode and obtain second biometric information, based at least on a voltage difference between the second electrode and the third electrode.
