RISShape Memory Alloy Expandable Pedicle Screw to Enhance Fixation in Osteoporotic Bone: Primary Design and Finite Element Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The properties of shape memory alloys, specifically the equiatomic intermetallic NiTi, are unique and significant in that they offer simple and effective solutions for some of the biomechanical ...
Nonlinear Control of a Shape Memory Alloy Actuated Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a nonlinear, robust control algorithm for accurate positioning of a single degree of freedom rotary manipulator actuated by Shape Memory Alloy (SMA). A model for an SMA ...
A Temperature-based Controller for a Shape Memory Alloy Actuator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a robust nonlinear control that uses a state variable estimator for control of a single degree of freedom rotary manipulator actuated by shape memory alloy (SMA) wire. A ...
