Capillarics - Pre-Programmed, Self-Powered Circuits Built from Microfluidic Capillary Elements
This paper obviously covers capillarics, which, from what I understand, are the physics of microfluidic circuits. At this level there are many parallels to circuit elements and thus here they present a symbolic table for how to reference capillaric circuits.
Passive microfluidics don’t require peripheral equipment to cause flow, and thus rely typically on capillary effects (passive systems are used often in diagnostics in lateral flow tests).
Autonomous capillary microfluidic systems have been proposed that self-regulate and self-power using a capillary pump and a capillary retention valve. In AMCS the capillary pressure is encoded in the geometry and surface properties, which drives liquid flow.
