Smart ring capable of measuring physiologic information

Abstract

A smart ring capable of measuring physiologic information includes a ring member and a physiologic sensing device. The physiologic sensing device has a circuit board provided in the ring member, to which a sensing unit and a processor are connected. The sensing unit has a light module and a sensor. The light module projects detecting lights to a subject who wears the ring member, and the detecting lights are reflected at different portions of subcutaneous tissue. The sensor senses reflections of the detecting lights to generate detecting signals accordingly. The processor receives the detecting signals from the sensor and coverts them into a physiologic value via a predetermined equation.
