Abstract

Provided is a physiological signal detection module which has a heating member and a multi-channel connector. The heating member maintains an electrode'"'"'s contact with a user skin at a constant temperature, and the multi-channel connector module for electrical connection transmits the physiological signal to an external physiological signal detection apparatus. It is possible to prevent the skin from being directly contacted with the electrode in the cold state and have a less impact given by a change of the impedance due to a skin temperature based on the change of the season and external temperature, so that the stable physiological signal can be detected without distortion.
