Untersuchungen zur Konstruktion und Montagetechnologie von integrationsfaehigen Membranpumpen, Ventil- und Sensorstrukturen fuer geregelte Mikrodosiereinrichtungen, insbesondere fuer medizinische Anwendungen

Abstract

The state of development and construction of an integrated micropump (8 mm height, 80 mm diameter) with piezoelectrical membrane drive for future application as a surgically implantable infusion apparatus is described in detail. The sandwich configuration chosen for the micropump allows the separation of pump system and electronical system. From the results obtained during experimental characterization of prototypical devices, topics of necessary future research and development work are derived: improvement of valve and pump efficiencies, and the reduction of the applied voltage amplitude (50-60 V).
