Claim Text:
1. A mobile terminal for measuring biological signals, comprising: an electrocardiogram electrode unit having a first electrode provided on a front surface of a body of the mobile terminal to enable contact with a first finger of a hand, and a second electrode and a third electrode each provided on a first side surface of the mobile terminal body to enable contact with an arm opposite to the hand and for measuring an electrocardiogram signal as a first biological signal through the first electrode, the second electrode, and the third electrode, wherein the second and third electrodes are positioned at the first side surface of the mobile terminal body; a reflective optical sensor unit having a light source for emitting light at tissue, and having a light receiver for receiving the emitted light reflected by the tissue, with the reflective optical sensor unit positioned at a second side surface on an opposite side of the mobile terminal body from the first side surface at which the second and third electrodes are positioned to enable contact with a second finger of the hand simultaneously with contact of the first electrode with the first finger and for optically measuring a pulse wave signal of the tissue from the received reflected light, and for generating a second biological signal from the pulse wave signal; a controller provided within the mobile terminal for analyzing the electrocardiogram signal received from the electrocardiogram electrode unit and the second biological signal received from the optical sensor unit to determine a pulse wave transmission time period; and a radio frequency (RF) unit for transmitting an analyzed result under the control of the controller, wherein at least one of the first electrode, second electrode, and third electrode is configured as a switch to trigger measuring the electrocardiogram signal and the pulse wave signal if one of the first electrode second electrode, and third electrode is touched by user.
