Apparatus and method for simultaneously measuring bio signals
First Claim
1. A bio signal measurement apparatus for simultaneously measuring a first bio signal generated in response to a stimulus signal and a second bio signal naturally generated by a human body, the apparatus comprising:
- a stimulus signal generating unit which generates the stimulus signal to be applied to the human body;
a sensing unit which contacts the human body and includes 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, the sensing unit being 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; and
a signal acquisition unit which separates and acquires the first and second bio signals from the at least one intermediate signal detected from the sensing unit.

Abstract
An apparatus and method for simultaneously measuring at least two different bio signals without interference are provided. The apparatus includes a stimulus signal generating unit generating the stimulus signal to be applied to a human body, 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 each intermediate signal, and a signal acquisition unit separating and acquiring the first and second bio signals from each intermediate signal detected from the sensing unit.
