Millifluidic Clock Uses Vacuum Transistors for Soft Seven-Segment Display
3D-printed millifluidic valves and resistors create a fully pneumatic soft clock; primary source reports fabrication adjustments for airtight prints and check-valve diodes.
A millifluidic device built from 3D-printed channels and silicone membranes forms a four-digit clock driven by negative-pressure logic gates equivalent to MOSFETs (https://spectrum.ieee.org/soft-robotics-2676960499). The design replicates fluidic transistors first detailed in early-2000s microfluidic literature and scales them to millimeter channels for higher flow rates. Logical 1 is defined as −60 kPa relative to atmosphere; a membrane pulled into a gate cavity opens source-drain paths.
