Abstract

Solid-state micropumps have constituted a promising market for point of care diagnostics, biomedical research and lab-on-a-chip test devices. Magnetic shape memory (MSM) alloy Ni-Mn-Ga elements have several desirable properties that make them attractive candidates for solid-state micropumps. Ni-Mn-Ga changes shape by up to 6% when exposed to a magnetic field. In this study, we have constructed a micropump using a Ni-Mn-Ga MSM element, which is driven by the rotation of a diametrically magnetized cylindrical magnet. The magnetic field creates a cavity on the MSM element. The cavity moves along the MSM element upon rotation of the cylindrical magnet and transports fluid. We will carry out systematic experiments measuring the pumping flow rate as a function of rotational speed of the magnet and discuss the results.
