Abstract

L'invention permet des mesures précises des variations dans le temps de la résistivité électrique ou de grandeurs liées à cette résistivité concernant un volume déterminé du corps soumis à un champ électromagnétique. Les électrodes 16, servant à capter le champ électrique, sont revêtues d'une fine membrane 15 les isolant du sérum physiologique 14 contenu dans une poche 20 que l'on applique sur la région 21 du corps soumis à l'examen. L'invention s'applique à toute investigation des phénomènes physiologiques ainsi qu'à l'exploration de toutes masses susceptibles de contenir plusieurs phases.
