Abstract

You may have seen something like magnetic shape memory (MSM) alloys at the movies. In Terminator 2, a “liquid metal” robot faces off against a more traditionally engineered robot. Although not humanoid, MSM alloy uses the same basic principle: it shape-shifts. Apply a magnetic field, and the material responds with a shape change. Remove the field, and the new shape remains. Apply a different magnetic field and the material re-forms into a new shape. Do this quickly and with purpose and you have a small motor, a micro-pump, or another small device. Invert the concept and you have a power generator or sensor. With such a behavior, MSM alloys could completely alter how we manufacture actuation and sensing devices. Products can be smaller, lighter and quieter since they have no moving parts to wear out. MSM alloys are a new engineering paradigm which requires new engineering approaches to technical solutions. This presentation will (i) introduce the scientific principles including magnetic anisotropy, deformation mechanisms, and magnetomechanics, (ii) outline design principles for MSM devices, and (iii) demonstrate MSM technology at the example of a micropump for drug delivery.
