SMART RING FOR MEASURING BIOMETRIC SIGNAL

WIPO Patent Application WO/2023/043194

A1

A smart ring for sensing a biometric signal is disclosed. A mart ring for sensing a biometric signal by being in contact with the skin, according to one aspect of the technical idea of the present disclosure, comprises: at least one light-emitting circuit including first to third light sources respectively generating light of first to third wavelengths incident on the inside of the skin at non-overlapping first to third points in time; a switch for controlling the at least one light-emitting circuit; first to third driving circuits for respectively controlling the first to third light sources of each light-emitting circuit; and a sensing circuit for acquiring reflected light which is output from the at least one light-emitting circuit and reflected from the inside of the skin.
