Abstract
By use of the vias a microfluidic autoregulator is fabricated comprising an origin of a fluid, a sink for the fluid, a main flow channel coupling the origin and the sink, a valve communicated to the main flow channel to selectively control flow of fluid therethrough, and means dependent on flow through the main flow channel for creating a pressure differential across the valve to at least partially activate the valve to control flow of fluid through the main flow channel. The means for dependent on flow for creating a pressure differential comprises either a dead-end detour channel from the flow channel to the valve, or a loop channel fed back to the control chamber of the valve.
