Physiological signal detection module, multi-channel connector module and physiological signal detection apparatus using the same
First Claim
1. A physiological signal detection module comprising:
- an electrode adapted to be in contact with a user skin to detect various physiological signals;
an electrode housing detachably connected to the electrode and having a printed circuit board (PCB) mounted with an operational amplifier for matching impedance of the skin with the electrode; and
a heating member coupled to the operational amplifier and interposed between the electrode and the electrode housing, and being supplied with an external power to increase the temperature of the electrode to a certain degree.

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.
