State-of-the-art of Shape Memory Actuators
نویسنده
چکیده
Shape-memory actuators are used where a large force and stroke are required and thermodynamic efficiency is not essential. Since the discovery of shape memory in titanium-nickel, a number of inventions have been made having applications in medicine, aerospace, automotive, and consumer products. These devices range in size from meters to micrometers. Sales are now more than a hundred million USD per year. This paper reviews some examples of past and present state-of-the-art applications. Some have been successful in the marketplace, others not, suggesting directions for future development.

Characterization of Constrained Aged Niti Strips for Using In Artificial Muscle Actuators (Technical Note)
Marvelous bending/straightening effects of two-way shape memory alloy (TWSMA) help their employment in design and manufacturing of new medical appliances. Constrained ageing with bending load scheme can induce two-way shape memory effect (TWSME). Scanning electron microscope (SEM) analysis, electrical resistivity measurement (ERM) and differential scanning calorimetry (DSC) are employed to dete...
متن کاملOn the Desing and Test of a Prototype of Biped Actuated by Shape Memory Alloys
In this paper the design of a biped robot actuated with Shape Memory Alloy (SMA) springs with minimum degrees of freedom is presented. SMA springs are a class of smart materials that are known for their high power to mass and volume ratios. It was shown that utilizing spring type of SMAs have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...
متن کاملExperimental Hysteresis Identification and Micro-position Control of a Shape-Memory-Alloy Rod Actuator
In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind. The current study aims at developing a micro-position control system ...
متن کاملNonlinear Analysis of a Flexible Beam Actuated by a Couple of Active SMA Wire Actuators
There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator can be placed at different offset distances from the beam, external actuators produce more bending moment and, consequently, considerable shape changes with the same magnitude...
متن کاملDesign, Fabrication and Intelligent Control of the Gripper Based on SMA Actuators
This paper presents the designing, simulation, fabrication and control of a gripper actuated by Shape Memory Alloy (SMA) wire. The presented gripper has the advantage of the small linear displacement of the slider connected to the SMA wire, and can convert the linear displacement into angular movement of the gripper fingers. In this study, design and simulation processes have been done by two p...
