... Abstract Integration of shape memory alloys (SMA) into actuator systems is still challenging, since mechanically and electrically anchoring are needed to provide stroke and trigger the shape memory effect (SME) in a controlled manner. A direct connection of SMA wires with printed circuit boards...

... Abstract Today, Nickel-Titanium (NiTi)-based shape memory alloy (SMA) wires are already used in a wide range of commercial actuator applications. The combination of their unique properties, such as their high energy density as well as their biocompatibility provides a broad range...

... Abstract For repeated actuation in shape memory alloy (SMA) actuators, a restoring force is needed to return to the initial starting position after activation. Therefore, SMA wires are often coupled with mechanical springs, which lengthen said wires again after activation through heating...

... as differences between the various test series, i.e., the influences of the changes in various parameters on the microstructure of the shape memory elements. SMA fatigue testing metallography Proceedings of the ASME 2021 Conference on Smart Materials, Adaptive Structures and Intelligent Systems...

... Abstract This paper presents a novel shape memory alloy (SMA) valve actuator concept for active venting in injection molding applications. The developed system can be used to expel air which is trapped during the injection molding process. If such air bubbles are not properly removed from...

... Abstract Automotive grille shutters are used to reduce the aerodynamic drag of the vehicle when cooling requirements are low by blocking a portion of the airflow through the condenser, radiator, and fan module (CRFM); the lower aerodynamic drag improves fuel economy. A passively actuated SMA...
