Ear type apparatus for measuring a bio signal and measuring method therefor
First Claim
1. An apparatus for measuring a bio signal, comprising:
- a bio signal measurement unit, which is insertable into an ear to be in close contact with an internal surface of the ear, the bio signal measurement unit having a photo plethysmography (PPG) measurement module for radiating light of different wavelengths onto the internal surface of the ear, detecting light transmitted through the ear, and outputting a PPG signal including bio information;
a control unit having a PPG signal processor for generating the bio information using the PPG signal measured by the PPG measurement module; and
an output unit for displaying the bio information generated from the control unit.
