a Schematic top-view of the chip for characterization. This chip is fabricated in 4 versions, each with a fixed flow channel width (250, 500, 750, or 1000 µm). The flow channel height is varied as a % of the flow channel width, indicated by the blue gradient. The control channel height is fixed per chip version, and the control channel width is varied as a % of the flow channel width. b Fabricated 4 versions of the chip, with the fixed flow channel width indicated. c Valve closures of the 4 chip versions at different actuation pressures (indicated by the 4 vertical bars at the bottom right: 1, 1.25, 1.5, 1.75 bar) (per bar, n = 9 to 12). The valve closures for the separate chip versions (250, 500, 750, and 1000 µm flow channel width) can be found in Supplementary information S.5
