Title (EN) FLUIDIC DEVICES WITH DIAPHRAGM VALVES
(FR) DISPOSITIF FLUIDIQUE A SOUPAPES A MEMBRANE
Abstract: front page image
(EN)This invention provides fluidic devices, in particular microfluidic devices, with diaphragm valves having low failure rates Low failure rates are achieved by inhibiting sticking of the diaphragm to Junctional surfaces such as valve seats, valve chamber and fluidic channels and conduits One way to implement this is to provide exposed surfaces facing the diaphragm, particularly valve seats, with a low energy material, such as a noble metal, a perfluoπnated polymer, a self-assembled monolayer, hard diamond, diamond-like carbon or a metal oxide In other embodiments, the valves are provided with ridges and the diaphragm is adhered to the fluidic or actuation layer with an adhesive material.
(FR)L'invention concerne des dispositifs fluidiques, plus précisément des dispositifs microfluidiques, à soupapes à membrane ayant de faibles taux de défaillances. On obtient ces taux en inhibant le collage de la membrane à des surfaces de jonction telles que sièges de soupapes, chambre de soupapes et canaux et conduits fluidiques, dont une mise en oeuvre consiste à présenter des surfaces exposées regardant la membrane, en particulier des sièges de soupapes, avec un matériau à faible énergie, par exemple un métal noble, un polymère perfluoné, une monocouche auto-assemblée, un diamant dur, un carbone de type diamant ou un oxyde de métal. Dans d'autres modes de réalisation, les soupapes sont pourvues de crêtes et la membrane adhère à la couche fluidique ou d'activation au moyen d'un matériau adhésif.
