摘要： A smart ring for sensing a biometric signal is provided. The smart ring for sensing a biometric signal by coming in contact with the skin includes at least one light-emitting circuit including first to third light sources that respectively generate light of first to third wavelengths incident on the inside of the skin at non-overlapping first to third points in time, a switch that controls each of the at least one light-emitting circuit, first to third driving circuits that respectively control the first to third light sources of each light-emitting circuit, and a sensing circuit configured to obtain reflected light that is output from the at least one light-emitting circuit and reflected from the inside of the skin.
