An electrode assembly for measuring bio-signals includes a body, a fastening member extending from the body and provided on one side of the body, the fastening member including a spring groove formed therein and an aperture penetrating therethrough, and a spring inserted into the spring groove. The aperture receives a fastening stud of a patch which is supplied from outside. The spring compresses the fastening stud received in the aperture such that the fastening member fixes the fastening stud thereto.

The inventive concept discloses a capacitive touch system and a coordinate extraction method thereof. The coordinate extraction method has operations of phases 1 and 2. First and second axis coordinates of a first frame are obtained by providing driving signals in a first direction selected in the first phase and performing a sensing in a second direction different from the first direction. First and second axis coordinates of a second frame are obtained by providing driving signals in a second direction selected in the second phase and performing a sensing in the first direction. First and second axis coordinates having a relatively high coordinate precision among the first and second axis coordinates may be finally determined as a touch coordinate. According to the inventive concept, since a touch sensing precision is improved to be strong against a noise, a touch coordinate is more precisely obtained.
