Abstract: Shape memory alloys are a class of soft actuators that can recover strain through a phase change and are capable of biomimetic motion. Despite the advantages of these alloys (e.g., high strength-to-weight ratios, inexpensive ...

Abstract: This paper presents a shape memory alloy actuator design using a bimorph structure capable of high-speed actuation and low power consumption. Two active layers of shape memory alloy wires are separated by a passive layer ...
