摘要： A flexible magnetic membrane based actuation system comprising magnetic nanoparticles loaded into a polymeric material such as polyurethane and adapted to actuation of to and fro pumping motions of the membrane under application of magnetic field on the magnetic nanoparticles loaded membrane. More particularly, the present invention is directed to the said nanoparticles-loaded polyurethane magnetic membrane based actuation system adapted to function as displacement membrane for various activities requiring such to and fro motion. The magnetic membrane actuation is adapted to be controlled using electronic equipments to regulate the rate, force and frequency of displacement pulses. The magnetic membrane is thus capable of providing a simple, bio-compatible and cost effective means for displacement/mechanical work to assist functioning of various gadgets/medical devices including function as an artificial support system for heart, non-responsive diaphragm or a non-responsive sphincter, and thus capable of wide industrial applications.
