Abstract
Cette invention concerne une bandelette de capteur électrochimique. Dans une bandelette de capteur à plusieurs électrodes, l'équilibrage des surfaces non actives ainsi que des surfaces actives d'électrodes améliore la précision et l'exactitude globale des mesures effectuées à l'aide de la bandelette de capteur. L'effet bénéfique de l'équilibrage des surfaces est plus prononcé avec des concentrations de glucose relativement faibles. Dans cette invention, l'exactitude et la reproductibilité de l'équilibrage des surfaces d'électrodes est améliorée du fait qu'on évite le chevauchement entre les électrodes et un revêtement diélectrique qui définit une surface d'exposition de l'électrode.
