Abstract:
Magnetic shape-memory alloys exhibit strong magneto-structural coupling enabling large magnetic-fieldinduced deformation. Local control of twinning via variable inhomogeneous magnetic fields initiates local reversible deformation. We applied this concept to build a valve-less micropump consisting of a Ni-Mn-Ga single crystal, a casing, and a rod magnet. The micropump successfully pumped fluid in opposite directions when the magnet was turned clockwise and counter clockwise. Here, we modify this micropump for application in rat a head stage, which would simultaneously monitor electroencephalograph data and deliver 0.5-5.0 μl of a drug solution at 100-500 nl/min directly to the rat’s brain.
