May 7, 2008 An innovative micro-pump makes it possible for tiny
quantities of liquid – such as medicines – to be dosed
accurately and flexibly. Active composites and an electronic
control mechanism ensure that the low-maintenance pump works
accurately – both forwards and backwards. Medicines sometimes
have to be administered in extremely small quantities. Just a
few tenths of a milliliter may be sufficient to give the patient
the ideal treatment. Micro-pumps greatly facilitate the dosage
of minute quantities. Pumps like these have been built and
constantly optimized for over 25 years. They find application in
numerous areas – from medical engineering to microproduction
technology – wherever tiny volumes have to be variably dosed
with extreme accuracy. However, these micro-pump systems are
usually not as flexible as desired: They often work in only one
direction, bubbles in the liquid impair their operation, they do
not tolerate bothersome particles, they have a fixed pump output
and they contain expendable pa
