Title (EN) FLUID DEVICE
(FR) DISPOSITIF À FLUIDE
Abstract:
(EN) A device including a substrate and a channel formed in a layer disposed on the substrate. The layer includes a cavitation layer and a passivation layer to mitigate the effects of hydrodynamic cavitation on a surface of the channel. The passivation and cavitation material and thickness are optimized thermally to nucleate and eject a bubble at low voltages. A resistive heating element is disposed within the channel that is activated to create a micro-fluidic pump to advance a fluid through the channel. A sensor is disposed within the channel to measure a characteristic of the fluid passing through the channel.
(FR) L’invention concerne un dispositif incluant un substrat et un canal formé dans une couche disposée sur le substrat. La couche inclut une couche de cavitation et une couche de passivation pour réduire les effets de cavitation hydrodynamique sur une surface du canal. Le matériau de passivation et de cavitation et l’épaisseur sont optimisés thermiquement pour nucléer et éjecter une bulle à de basses tensions. Un élément chauffant résistif est disposé dans le canal qui est activé pour créer une pompe microfluidique pour faire avancer un fluide dans le canal. Un capteur est disposé dans le canal pour mesurer une caractéristique du fluide traversant le canal.
