Abstract
The invention relates to a system and an implementation method for pumping a fluid, the system comprising: a pump comprising a flexible membrane which has two opposing surfaces, the membrane comprising a spatially rotating permanent magnetization structure, a rigid support means to which at least a portion of the lower surface of the membrane is attached, a source of a magnetic field which is capable of generating a magnetic drive field at the location of the membrane, the magnetic drive field having a substantially homogeneous orientation.
Claims17
A system for pumping a fluid, said system comprising:
- a pump comprising:
- an inlet and an outlet for respectively introducing and extracting said fluid capable of being pumped,
- a flexible membrane having two opposite surfaces, said membrane comprising a spatially rotating permanent magnetization structure,
- a rigid support means on which is fixed at least part of one of said surfaces of said membrane,
- a source of a magnetic field capable of generating a driving magnetic field at the place where said membrane is located, said driving magnetic field having a substantially homogeneous orientation, said membrane being capable to deform, under the effect of said driving magnetic field, according to a ripple having alternately one or more concave parts and one or more convex parts, the ripple being able to move under the effect of said driving magnetic field, said fluid capable of being pumped between said inlet and said outlet being located at least between one of said surfaces of said membrane and said rigid support means.
