Abstract
An example fluidic micro electromechanical system may include a substrate and a first layer supported by the substrate. The first layer forms sides of a chamber, a passage through one of the sides and a chamber and a check valve leaf. The check valve leaf is pivotable about an axis nonparallel to the substrate to open and close the passage. The system may further include a second layer over the chamber, an opening into the chamber and a resistor supported within the chamber.
