Abstract
An asymmetric micro pump may be adapted to provide a greater fluid compression between input and output ports of the micro pump, as well as increased flow rate due to higher actuation frequency. In some instances, asymmetric dual diaphragm micro pumps may be combined into assemblies to provide increased pressure build, improved pumping volume, or both, as desired.
