Title
(EN) EVALUATING IMPEDANCE MEASUREMENTS
(FR) ANALYSE DE MESURES D’IMPÉDANCE
Abstract
(EN)
An impedance measurement system for performing a bioimpedance measurement on a biological subject, the system including a signal generator configured to apply alternating signals to at least part of the biological subject at a plurality of different frequencies, a sensor configured to measure response signals from the biological subject and one or more electronic processing devices that determine impedance values obtained at the plurality of different frequencies using the measured response signals, calculate an impedance curve using a curve fitting algorithm, determine a deviation of the impedance curve from the impedance measurements and use the deviation to perform an evaluation of the impedance measurements.
(FR)
Système de mesure d'impédance pour la mise en œuvre d'une mesure de bio-impédance chez un sujet biologique, le système comprenant un générateur de signaux configuré pour appliquer des signaux alternatifs présentant de multiples fréquences différentes à au moins une partie du corps du sujet biologique, un capteur configuré pour mesurer des signaux de réponse provenant du sujet biologique et un ou plusieurs dispositifs de traitement électronique qui déterminent les valeurs d'impédance obtenues avec les multiples fréquences différentes à l'aide des signaux de réponse mesurés, qui calculent une courbe d'impédance à l'aide d'un algorithme d'ajustement de courbe, qui déterminent un écart de la courbe d'impédance par rapport aux mesures d'impédance et qui utilisent l'écart pour effectuer une analyse des mesures d'impédance.
