Title
(EN) MULTIPLEXED SENSOR ARRAY
(FR) RÉSEAU DE CAPTEURS MULTIPLEXÉ
Abstract
(EN) A sensor array, comprising: a plurality of sensors electrically connected in series or in parallel, each of the plurality of sensors operable to generate an individual electrical signal; a multiplexing scheme generator operable to generate a multiplexing scheme; a modulation system connected to the multiplexing scheme generator and operable to selectively reverse the polarity of each of the plurality of sensors for each of a plurality of samples; a readout device operable to sequentially read a plurality of output signals of the plurality of electrically connected sensors, wherein the number of samples is greater than or equal to the number of sensors and wherein one or more electrical signals of the plurality of sensors are readout as one electrical signal; and a demultiplexer operable to receive the output electrical signals and to determine the individual electrical signals of each of the plurality of sensors based on the multiplexing scheme.
(FR) L'invention concerne un réseau de capteurs comprenant : une pluralité de capteurs connectés électriquement en série ou en parallèle, chacun des capteurs dans ladite pluralité de capteurs permettant de produire un signal électrique individuel ; un générateur de mécanisme de multiplexage permettant de produire un mécanisme de multiplexage ; un système de modulation connecté au générateur de mécanisme de multiplexage et permettant d'inverser sélectivement la polarité de chaque capteur dans la pluralité de capteurs, pour chaque échantillon dans une pluralité d'échantillons ; un dispositif de lecture permettant de lire séquentiellement une pluralité de signaux de sortie de la pluralité de capteurs connectés électriquement, le nombre des échantillons étant égal ou supérieur au nombre des capteurs et un ou plusieurs signaux électriques, sur la pluralité de capteurs, étant lus sous la forme d'un signal électrique ; et un démultiplexeur permettant de recevoir les signaux électriques de sortie et de déterminer les signaux électriques individuels de chaque capteur dans la pluralité de capteurs, sur la base du mécanisme de multiplexage.
