The electrical transport properties of shape memory alloys for sensing/actuating

Shape Memory Alloys (SMAs) are known for their smart properties connected to a thermoelastic martensitic transformation, which gives rise to the pseudoelasticity and the shape memory effect. High strain values can be built up and recovered during …

The electric resistance of shape memory alloys in the pseudoelastic regime

The electric resistance, sensitively dependent on the electronic structure and currently used to detect transformation temperatures in shape memory alloys, deserves attention also in the stress transformation domain. In fact, the electric resistance …

The electrical resistance properties of shape memory alloys

Shape memory alloys are known for their ability to build up large deformations under an applied stress, either in martensitic phase or in the pseudoelastic region. The electrical resistance of shape memory alloys, traditionally used to define the …
