Abstract
The measuring head enables the production of measuring signals relating to electrical activity and measuring signals relating to an ionic or physico-chemical activity, notably pH, and is designed to be located on or in parts of a living body, notably on the head of an unborn infant. It comprises an insulating body bearing fastening claws. At the moment of positioning, the insulating body introduces actively an electrode sensitive to the electrical activity and at least one electrode sensitive to an ionic or physical activity. These electrodes are constructed in needle form, body body having also a reference electrode associated with the electrode sensitive to the ionic or physical activity.
