The first sensor 110 includes a first light emitting unit (not shown) and a first light receiving unit (not shown), and the second sensor 120 includes a second light emitting unit (not shown) and a second light receiving unit (not shown). It is preferable to include.

The first sensor 110 and the second sensor 120 receive a driving instruction from the entire control unit (not shown) and operate as follows. IN1 means driving instruction of the whole controller (not shown).

The first sensor 110 senses the finger artery wave by irradiating predetermined light onto one end 112 of the finger 100 and sensing the reflected light among the irradiated light. In this case, the light irradiation is made by the first light emitting unit (not shown), the light sensing is preferably made by the first light receiving unit (not shown).

As shown in FIG. 1B, the first sensor 110 is preferably attached to one end 112 of the finger 100.

The second sensor 120 senses the finger artery wave at the other end 122 spaced apart from the one end 112 of the finger 100 by a predetermined distance. The second sensor 120 senses the finger artery wave by irradiating a predetermined light to the other end 122 of the finger 100 and sensing the reflected light among the irradiated light.

Aortic waves (not shown) and thigh reflected waves (not shown) exist in the finger artery wave. Aortic wave (not shown) refers to a pulse wave generated when the left ventricle (not shown) of the heart (not shown) contracts. The femoral reflection wave (not shown) refers to a pulse wave generated by the aortic wave reflected from the femoral artery.
