*Correspondence: Marcelo J. Dapino, 201 West 19th Avenue, Columbus, OH 43210, USA e-mail: [email protected] Shape memory composites (SMCs) based on shape memory alloys (SMAs) and shape memory polymers (SMPs) allow many design possibilities due to their controllable temperature-dependent mechanical properties. The complementary characteristics of SMAs and SMPs can be utilized in systems with shap...

The attractive properties of shape memory alloys (SMA), especially their high energy density, steadily expand the range applications in which SMA wires represent alternative actuator components. Industrial particular, oftentimes require large forces, scale with diameter wires. higher required force, larger total effective cross-sectional area is needed. Increasing wire results worse dynamics du...

In the field of micromechatronics, microrobotics and specially microfactories, active materials are used in most cases. They permit high resolution and distributed actuation. In this area, Magnetic Shape Memory Alloys (MSMA) are possible candidates. If a lot of studies deal with MSMA, only few applications use them until now. MSMA are attractive active materials because they have large strain (...

This study is aimed at assessing the feasibility of employing an innovative, smart-material-based control effector for inflatable wing. A shape memory alloy (SMA) actuator primarily investigated as a in this work its advantages simple actuation mechanism and high force-to-weight ratio. paper presents design, strategy simulation results SMA used stability augmentation system small-scale prototyp...

A combined theoretical/experimental study of the heat transfer in thermoelectric Shape Memory Alloy (SMA) actuators is undertaken in this paper. A one-dimensional model of a thermoelectric unit cell with a SMA junction is developed rst and the transient temperatures in the SMA are evaluated for di erent applied electric current densities. As a rst step towards the design of an actuator, a therm...

A three-degree-of-freedom actuator was implemented using shape memory metals (SMA) for two-dimensional movement. In its design, a CAD software used, analyzing the movements made by ball joint, obtaining conical body with circular base. For movement, one-way SMA spring arrangement as opposed to two-way one displacement in each of XY axes, and rotation means bearing coupled axis that allows direc...
