Abstract | A digital microfluidic device comprising a consumable microfluidic receptacle including a first plate and a second plate spaced apart from the first plate, the microfluidic receptacle to receive a polar liquid droplet between the respective first and second plates. The second plate comprises a first portion to receive charges from a charge applicator, to produce an electric field between the second plate and the first plate at a position adjacent the liquid droplet to pull the liquid droplet through the microfluidic receptacle. A vibration element is coupled to a portion of the receptacle to apply a mechanical vibration acceleration force, at least during droplet movement, which is substantially greater than a gravitational acceleration force.
Dispositif microfluidique numérique comprenant un réceptacle microfluidique consommable comprenant un premier plateau et un second plateau espacé du premier plateau, le réceptacle microfluidique devant recevoir une gouttelette de liquide polaire entre les premier et second plateaux respectifs. Le second plateau comprend une première partie destinée à recevoir des charges provenant d'un applicateur de charges, afin de produire un champ électrique entre le second plateau et le premier plateau à une position adjacente à la gouttelette de liquide pour tirer la gouttelette de liquide à travers le réceptacle microfluidique. Un élément de vibration est couplé à une partie du réceptacle pour appliquer une force d'accélération de vibration mécanique, au moins pendant le mouvement des gouttelettes, sensiblement supérieure à une force d'accélération gravitationnelle. |
