Abstract
The influence of phase transformations on the actuation capacity of microlayered architectures based on shape memory alloys is presented based on models developed based on the analysis of the phase transformations in each layer and on their contribution to the stress in the fil-substrate architecture. The analysis of the phenomena associated with the martensitic transformation allows the selection of the alloy composition to obtain a tuneable actuation in the desired temperature range as well as the profile of this operation based on the type of substrate used and its geometry as well as the fabrication parameters. The prediction of a microactuation profile is described for bimorph architectures with a film consisting of one or more shape memory alloy layers
