1. A sensor for measuring a physiological signal from outside a body, the sensor comprising:
- a flexible substrate, which is permeable to moisture, and which has a first surface and a second surface opposite to the first surface,at least one electrode attached to said substrate and having a signalling surface, which faces in the same direction as the first surface of the flexible substrate,a signal transmission conductor connected electrically to said electrode, wherein an entire length of the signal transmission conductor is attached in a watertight manner to the second surface of the substrate, the signal transmission conductor comprising a conductive substance applied in fluid or solid form; and
an installation zone, onto which an electronics module is removably attachable, is formed on the signal transmission conductor, the installation zone being provided with metallic contact wires integrated on an inner circumference thereof;
wherein said signal transmission conductor is connected electrically to the metallic contact wires situated in the installation zone, so that when the electronics module is attached onto the installation zone, the metallic contact wires in the installation zone make electrical contact with the electronics module.
