Abstract

Actuation is one the most prosiming fields for industrial application of SMA based devices. Since most of the present industrial applications are related to medical devices, there is a lack of info and standardisation on the charactheristaion in actuation related applications.

This talk will give hints on the complete characterisation route, from the ingot to the finished wire in use condition, and on the influence of ingot purity on actaution related performances. Namely, focus will be given on the study of the actuation - de-actuation cycle, on the fatgue behaviour, and on a new concept of 100 % process and product control.

Specific focus will also be given on the definition of actuation paremters, and on the influence of these parameters (stroke, feeding current, load) on the fatigue behaviour.
