Abstract
A fluid pump comprising one or two cavities which, in use, contains a fluid to be pumped, the chamber or chambers having a substantially cylindrical shape bounded by first and second end walls and a side wall; an actuator which, in use, causes oscillatory motion of the first end wall(s) in a direction substantially perpendicular to the plane of the first end wall(s); and whereby, in use, these axial oscillations of the end walls drive radial oscillations of the fluid pressure in the main cavity; and wherein an isolator forms at least a portion of the first end wall between the actuator and the side wall and includes conductive tracks, wherein electrical connection is made to the actuator via the conductive tracks included within the isolator.
