An electrode holding arrangement (100) for biosignal acquisition or stimulation, comprising: a piece of flexible material (20) adapted for being fixed to a certain body part and at least one electrode spring element (30) created within the piece of flexible material (20) by cutting out a certain geometric profile (40) from said flexible material (20), and configured for, when the piece of flexible material (20) is fixed to a body part (97, 98) and an electrode (60) is attached to the at least one electrode spring element and is positioned on a body tissue surface (80A) so that it generates a force (FE) that makes the electrode spring element protrude outside the horizontal plane (H) of the plastic piece of flexible material, generating a force (FC) that presses the electrode (60) against the body tissue surface (80A).
