We have been conducting research in micro-pumping technology primarily
devoted to the development of pumps that operate in the 10 to 1600
micro-liter per minute flow rate range. We have been particularly
interested in reciprocating pumps based on inlet and outlet valves
that have no moving parts. Such valves have a number of advantages
given their small dimensions. These valves do not require gaskets,
hinges or sealing surfaces. In addition, these valves may be ideal
for pumping fluids that contain biological material such as living
cells or non-organic particulates that might interfere with valves
that require closure to work properly. You can
step through
the poster presentation or you can click on the poster itself for
more information on fabrication and principles of operation.
