  • Microfluidic device
    Patent number: 11311878
    Abstract: The invention relates to a microfluidic device comprising at least one element (1) of magnetic shape memory (MSM) material for handling of a fluid flow, the MSM element (1) being controlled by a magnetic field. The device comprises elastic material (2) between the handled fluid and the MSM element (1), and that the magnetic field is arranged to form a local shrinkage to the MSM element (1) which together with the elastic material (2) form a shrinkage cavity (3) in a location where the magnetic field is applied to the MSM element. Preferably, the microfluidic device is connected to a lab-on-a-chip, and it can act as one of the followings: a pump, vacuum pump, compressor, refrigerator, valve, manifold, dozer, mixer.
