So that the light beam returned from the second light transmitting region 1112 can be directly transmitted to the photosensitive member 140 through the second light guiding member 180.

The light emitting element 130 may be a light emitting diode (LightEmitting Diode, LED), the light emitting element 130 emits a light beam with a certain wavelength to irradiate on the skin surface, the reflected light intensity changes based on the absorption principle of blood to light, the light sensing element 140 may be a Photo Detector (PD), and the change of the reflected light intensity is measured by the light emitting element 130 to analyze and monitor the heart rate, so as to obtain real-time heart rate data.

When the wearable device is used for measuring heart rate, the light emitting element 130 emits light beams with a certain wavelength, the light beams enter the human tissue 20 through the first light guide element 170 and the first light transmission area 1111, the reflected light intensity changes along with the absorption principle of blood on the basis of the light beams, the light beams return to the photosensitive element 140 through the second light transmission area 1112 and the second light guide element 180, and the light beams do not escape from an air gap in the whole process based on the actions of the first light guide element 170 and the second light guide element 180.
