Abstract

A micropump for pumping a fluid, the pump comprising: a tube formed from a piezoelectric material and having inner and outer surfaces; a plurality of electrodes electrifiable to generate vibrations in the tube; and at least one voltage source that applies voltages to the electrodes to generate a displacement traveling wave that propagates along the tube and causes fluid in the tube to flow through the tube.
