Abstract
(EN)
A microfluidic device (100), a microfluidic detection assembly, and a detection method (900) for the microfluidic device. The microfluidic device (100) comprises a first substrate (120) and a second substrate (130), wherein the first substrate (120) and the second substrate (130) are arranged opposite to each other so as to define a channel for liquid flow between the first substrate (120) and the second substrate (130); the first substrate (120) comprises a base substrate (114) and a plurality of control assemblies (110) arranged on the base substrate (114) along the extension direction of the channel; each control assembly (110) comprises: a first electrode (111), a second electrode (112), and a plurality of coils (113); the first electrodes (111) are used to input a current to the plurality of coils, and the plurality of coils (113) are connected in parallel in between the second electrodes (112). The present microfluidic device reduces the calorific value of the microfluidic device by means of connecting the coils in parallel with the second electrodes, which may improve the detection quality.

L'invention concerne un dispositif microfluidique (100), un ensemble de détection microfluidique et un procédé de détection (900) pour le dispositif microfluidique. Le dispositif microfluidique (100) comprend un premier substrat (120) et un second substrat (130), le premier substrat (120) et le second substrat (130) sont disposés à l'opposé l'un de l'autre de manière à définir un canal pour un écoulement de liquide entre le premier substrat (120) et le second substrat (130) ; le premier substrat (120) comprend un substrat de base (114) et une pluralité d'ensembles de commandes (110) disposée sur le substrat de base (114) dans la direction d'extension du canal ; chaque ensemble de commandes (110) comprend : une première électrode (111), une seconde électrode (112), et une pluralité de bobines (113) ; les premières électrodes (111) sont utilisées pour laisser entrer un courant dans la pluralité de bobines, et la pluralité de bobines (113) est reliée en parallèle entre les secondes électrodes (112). Grâce à la connexion des bobines en parallèle avec les secondes électrodes, la valeur calorifique du présent dispositif microfluidique est réduite, ce qui peut améliorer la qualité de la détection.
