The shape memory alloy (SMA) actuator is widely used in aerospace, medical and robot
fields because of its advantages of low driving voltage, large driving force, no noise and high …

Most materials possess microstructural features at small length scales which are either
stationary, such as grains and grain boundaries, phases and phase boundaries …

Purpose The paper aims to propose a novel dual-stage shape memory alloy (SMA) actuated
gripper (DAG), of which the grasp performance is improved through primary and secondary …

Multifunctional materials have tremendous potential for engineering applications as they are
able to convert mechanical to electromagnetic energy and vice-versa. One of the features of …

Shape memory alloys (SMAs) are a class of smart materials that exhibit a macroscopic
contraction of up to 5% when heated via an electric current. This effect can be exploited for …

The application of shape memory alloy (SMA) actuated soft grippers is limited by their slow
recovery speed. In order to further expand their application range, as one of the solutions to …

In this paper, a multi-posture actuator (MPA) composed of VT-type bidirectional deflection
fishbone-like modules (VBFM) based on shape memory alloy (SMA) wires is proposed for …

In this letter, a hybrid model for single-crystal Shape Memory Alloy (SMA) wire actuators is
presented. The result is based on a mathematical reformulation of the Müller-Achenbach …
