Abstract
The invention provides a pump with a transducer comprising a laminate with a film of a dielectric polymer material arranged between first and second layers of an electrically conductive material so that it is deflectable in response to an electrical field applied between the layers, wherein the laminate is arranged to cause a pumping action upon deflection of the film. The invention further provides a control system for a pump.
