Method and device to measure biosignal
First Claim
1. A biosignal measurement device, comprising:
- a first signal connector capable of removably attaching to an electrode unit that is configured to sense a biosignal, wherein the first signal connector is configured to receive the biosignal from the electrode unit;
a power supplier configured to supply power to the electrode unit, in response to the power supplier being connected to the electrode unit; and
a signal processor configured to process the biosignal received by the first signal connector, to maintain a signal processing frequency band of a filter when the power supplier is disconnected from the electrode unit, and to change the signal processing frequency band of the filter when the power supplier is connected to the electrode unit.

Abstract
Provided is a biosignal measurement method and device that may measure a biosignal by connecting a simple electrode or a capacitive coupling active electrode to a biosignal processor to analyze the biosignal. The biosignal processor may change a frequency band in which the biosignal is to be filtered based on a type of the connected electrode. The biosignal measurement device includes a first signal connector capable of removably attaching to an electrode unit that is configured to sense a biosignal, wherein the first signal connector is configured to receive the biosignal from the electrode unit; a power supplier configured to supply power to the electrode unit in response to the power supplier being connected to the electrode unit; and a signal processor configured to process the biosignal received by the first signal connector.
