Electronic device for sensing biometric information and control method thereof

An electronic device comprising:

• 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, the first electrode and the second electrode having a cylindrical shape, and the second electrode being located inside the first electrode;
• a second pad including at least a third electrode;
• and
• a processor configured to control the at least one communication circuit, the first pad, and the second pad,
• wherein the processor is configured to:
• obtain the first biometric information, based at least on an electric current induced by applying a first specified voltage between the first electrode and the second electrode,
• obtain second biometric information, based at least on a voltage difference between the second electrode and the third electrode, and
• obtain third biometric information based on an electric current between the second and third electrodes induced by applying second specified voltage between the second electrode and the third electrode.
