MICROFLUIDIC DEVICE FOR CONTROLLING PNEUMATIC MICROVALVES

摘要

The present invention relates to a microfluidic device (10) for independently controlling a plurality of pneumatic microvalves (70), the microfluidic device (10) being couplable to a pressure source and comprising: (i) a first substrate (20); (ii) a flexible membrane (30) covering the first substrate (20); (iii) a second substrate (40) covering the flexible membrane (30); (iv) one or more fluidic channels (50) at least partially defined in the first substrate (20); (v) a pressure line (60) coupled to the pressure source and branching into a plurality of pressure channels (63), the pressure channels (63) being at least partially defined in the second substrate (40); (vi) the plurality of pneumatic microvalves (70); and (vii) at least one pressure control switch (80) per pressure channel (63), comprising an actuator (90) for bending the flexible membrane (30); wherein each actuator (90) can be operated independently.
