摘要： An apparatus and method to detect a blood flow signal free from a motion artifact, and a stress test apparatus using the same, enhance data reliability of the blood flow signal by removing the motion artifact from the blood flow signal detected by photo-plethysmography. The apparatus to detect the blood flow signal includes a base pattern correlation coefficient calculating unit to determine peak points in the blood flow signal sensed from a body of an examinee using a blood flow sensing unit, and to calculate correlation coefficients of each peak point using a predetermined base pattern, and a motion artifact processing unit to determine the motion artifact using the calculated correlation coefficients and to remove the motion artifact from the blood flow signal. Thus, reliability of the blood flow signal is enhanced by effectively removing the motion artifact from the blood flow signal detected by the photo-plethysmography.

摘要： An apparatus and method for perceiving a physical and emotional state, which allows easy attachment to and detachment from a human body, and through which a bio-signal is simply detected, are provided. The apparatus includes a bio-signal detection part attached to a predetermined portion of a body for performing analog signal processing on at least one bio-signal detected from the body and outputting the processed bio-signal, and a bio-signal recognizing part for performing digital signal processing on the processed bio-signal received from the bio-signal detection part, perceiving the physical and emotional state from the result of the digital signal processing, and representing the physical and emotional state. Accordingly, the apparatus can be conveniently attached to a predetermined portion of a user's body, a bio-signal transmitted wirelessly or through a wire can be easily detected, a physical and emotional state which is perceived based on the detected bio-signal can be reported to the user, and a rapidly changing emotional state or an emotional state which remains for a long time can be perceived in real time.
