Development of a peristaltic micropump based on a composite material with piezo elements

In the PEMI project a peristaltic micropump is realized consisting of flat piezo elements as active parts. For that purpose the technology of an active composite material for the single elements has been developed.  The peristaltic pumping principle is analog to the material transportation in the intestine or the gullet.  The individually addressable piezo elements are assembled to yield a flat tube consisting of two active membranes positioned on top of each other. The side walls of the tube move wavelike and so effect material transport.
The objective of the project is the realization of a peristaltic micropump for the use in medical technology or in the field of micro dosing technology for adhesives respectively.
