  • Patent number: 10500587
    Abstract: A micropump includes a body with an inlet and an outlet defined therein. A channel connects the inlet to the outlet. The micropump further includes a magnetic shape memory (MSM) alloy positioned within the channel. The MSM alloy selectively forms a barrier between the inlet and the outlet. The micropump also includes an electrode and/or a transparent window positioned along a surface of the channel. A cavity is selectively formed within a surface of the MSM alloy due to a magnetic field. The cavity is selectively moveable between a first position adjacent to the inlet, a second position adjacent to the electrode and/or the transparent window, and a third position adjacent to the outlet, by altering the magnetic field. By altering a magnetic field applied to the MSM alloy, a fluid may be pumped from the inlet to the electrode and/or the transparent window where the fluid may be analyzed. The fluid may be subsequently pumped to the outlet.
