Title
(EN) SYSTEM AND BIO-IMPLANTABLE CHIP FOR MEASURING ELECTRICAL RESISTANCE FOR INTEGRITY MONITORING, AND MANUFACTURING METHOD
(FR) SYSTÈME ET PUCE BIO-IMPLANTABLE POUR LA MESURE D'UNE RÉSISTANCE ÉLECTRIQUE POUR UNE SURVEILLANCE D'INTÉGRITÉ, ET PROCÉDÉ DE FABRICATION
Abstract
(EN)
The present invention relates generally to a system, a sensor, a manufacturing method and a bio-implantable chip for measuring electrical resistance for integrity monitoring of bio-implantable chips. In a first aspect, there is provided a resistance measurement system based on a node, comprising a stack of layers, a switching unit arranged for connecting and disconnecting a charge holding capacitor of said node; a voltage sensor arranged for determining a voltage level of said node: and a control unit, arranged for controlling said switching unit to switch said node between two states and being arranged for determining a discharge time of a discharge state, wherein said discharge time is derived from counting clock pulses between switching said node from said first to said second state and said voltage sensor determining said node to drop below a predetermined discharge voltage level; a calculation unit for calculating said electrical resistance.

La présente invention concerne de manière générale un système, un capteur, un procédé de fabrication et une puce bio-implantable pour la mesure d'une résistance électrique pour la surveillance d'intégrité de puces bio-implantables. Selon un premier aspect, l'invention concerne un système de mesure de résistance reposant sur un nœud comprenant une pile de couches, une unité de commutation agencée pour connecter et déconnecter un condensateur de maintien de charge dudit nœud; un capteur de tension agencé pour déterminer un niveau de tension dudit nœud : et une unité de commande agencée pour commander ladite unité de commutation pour commuter ledit nœud entre deux états et étant agencée pour déterminer un temps de décharge d'un état de décharge, ledit temps de décharge étant dérivé des impulsions d'horloge de comptage entre la commutation dudit nœud dudit premier audit second état et ledit capteur de tension déterminant ledit nœud pour sa chute au-dessous d'un niveau de tension de décharge prédéterminé; une unité de calcul destinée à calculer ladite résistance électrique.
