Make a Soft Digital Clock Tick With Millifluidics

Electrons are great . We use them to move vehicles, illuminate cities, and, of course, compute. But computation is not confined to the world of electronics. And shifting to alternative nonelectronic realms can unlock unique advantages: Photonic chips, for instance, process information with light while generating little heat. Another compelling alternative is fluidics , which uses pressurized gases or liquids to build logic circuits. Pioneered in the 1960s but sidelined by microchips, the field r
