A multi-channel bio-med electric signals capturing device includes: a detection channel unit, a control unit, a voice signal generator and a computer device. The detection channel unit is provided to detect bioelectric signals produced from human body and amplify the same. The control unit is provided to capture the amplified bio-med electric signals based on a frequency conforming to a computer acceptable audient signal. The voice signal generator transmits the captured amplified bio-med electric signals to a microphone of the computer device, whereby a recording program built in the computer device records the input audient signal as a voice file. Accordingly, the user is able to monitor the bio-med electric signals by easily and simply using a computer device.
