Abstract
The size effect in triggering the actuation of NiTi shape memory alloys directly by electrical current is investigated. Wire/rod is taken as an example in this study to show the relationship between the diameter of shape memory alloy wire/rod and the required current/power for actuation, and in the case of cyclic operation, achievable frequency. Through a few case studies, it is revealed that by presenting on logarithmic scale, the major operating characteristics can be quickly estimated as linear functions of wire/rod diameter.
