Apparatus and method for simultaneously measuring bio signals

A bio signal measurement method of simultaneously measuring a first bio signal generated in response to a stimulus signal and a second bio signal naturally generated in a human body, the method comprising:

• providing a sensing unit contacting the human body, including a plurality of electrodes to which the stimulus signal is applied and from which at least one intermediate signal containing the first and second bio signals is detected, configured to share at least one of the plurality of electrodes to apply the stimulus signal or to detect the at least one intermediate signal;
• generating the stimulus signal to be applied to the human body;
• and
• separating and acquiring the first and second bio signals from the at least one intermediate signal detected by the sensing unit.

A computer-readable recording medium having recorded thereon a computer-readable program for performing a bio signal measurement method of simultaneously measuring a first bio signal generated in response to a stimulus signal and a second bio signal naturally generated, the method comprising:
