Title
(EN) MICRONEEDLE ARRAY SENSOR PATCH FOR CONTINUOUS MULTI-ANALYTE DETECTION
(FR) PATCH CAPTEUR À RÉSEAU DE MICRO-AIGUILLES POUR LA DÉTECTION CONTINUE D'ANALYTES MULTIPLES
Abstract
(EN) Disclosed are systems, devices and methods for continuous and simultaneous monitoring of multiple analytes within interstitial fluid by an integrated system for a microneedle array sensor platform. In some aspects, the device includes a microneedle array sensor unit, an electronics unit and a housing structure. The electronics unit is in electrical communication with an array of electrode probe structures via an array of surface-mount, spring loaded pins, and the electronics unit includes a power source, a data processing unit, and a wireless transmitter. The housing structure is configured to encase, at least partially, the microneedle array sensor unit and the electronics unit, where the array of microneedles is exposed from a side of the housing structure. The device can be configured as a patch worn on skin of a patient user.
(FR) Sont divulgués des systèmes, des dispositifs et des procédés pour la surveillance continue et simultanée d'analytes multiples dans un fluide interstitiel par un système intégré pour une plateforme de capteur à réseau de micro-aiguilles. Selon certains aspects, le dispositif comprend une unité de capteurs à réseau de micro-aiguilles, une unité électronique et une structure de boîtier. L'unité électronique est en communication électrique avec un réseau de structures de sondes électrodes par l'intermédiaire d'un réseau de broches à ressort montées en surface, et l'unité électronique comprend une source d'alimentation, une unité de traitement de données et un émetteur sans fil. La structure de boîtier est configurée pour envelopper, au moins partiellement, l'unité capteur à réseau de micro-aiguilles et l'unité électronique, le réseau de micro-aiguilles étant exposé depuis un côté de la structure de boîtier. Le dispositif peut être configuré sous la forme d'un patch porté sur la peau d'un patient utilisateur.
