Title
(EN) IMPEDANCE BASED WOUND HEALING MONITOR
(FR) MONITEUR DE CICATRISATION DE PLAIE BASÉ SUR L'IMPÉDANCE
front page image
Abstract
(EN) A method includes applying an electrical signal to a tissue and measuring an impedance of the tissue based on the applied electrical signal. The method further includes determining information indicative of a stage of wound healing based on the impedance and outputting information indicative of the stage of wound healing.
(FR) L'invention concerne une méthode consistant à appliquer un signal électrique sur un tissu et à mesurer l'impédance du tissu en fonction du signal électrique appliqué. Cette méthode consiste également à déterminer des informations indiquant un stade de cicatrisation de plaie en fonction de l'impédance, et à émettre en sortie des informations indiquant le stade de cicatrisation de la plaie.
