Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to an attraction-attachable electrically conductive pad, and more particularly to an electrically conductive pad that can be held in a condition of being in contact engagement with a surface of a human body to conduct detection without accident or undesired position shifting and achieves comfortableness of being worn so as to be fit to operations of physiological detection.

2. Description of Related Art

Recently, high-tech manufacturers have actively engaged in studies of installing electrically conductive pads in fabric or woven and knitted articles to detect physiological signals when worn in order to get aware of the states of physical functionality and also for monitoring and recording.

Such a conductive pad is put in contact with the surface of a human body, but such a conductive pad is fixed in the fabric so that movement or activity of the human body would cause the fabric to move and displacement results and would inevitably cause interruption of signal or abnormal signal for the detection signal generated by the conductive pad that is in operation for detection on the body surface. This, once happening, requires re-positioning of the conductive pad, or would make it necessary for the human body to keep still in order to allow for smooth performance of detection of physiological signals.

Thus, in view of the above problems, those known devices or articles are still defective and are not designs of perfectness, and further improvements are necessary.
