Abstract
A microsized pump is set forth. It comprises a substrate which at least partially defines one or more walls of a longitudinally extending tunnel. The tunnel has a vibratable wall portion. A sonic energy generator is positioned in sonic energy transmitting relation to the vibratable wall portion. The sonic energy generator is adapted to generate elastic waves which travel along the longitudinal extension of the tunnel. The pump is useful for moving material along the tunnel whereby chemical and biological analysis and reactions can be carried out on a micro scale.
