...WonHee Kim; Brian M. Barnes; Jonathan E. Luntz; Diann E. Brei The high energy density actuation potential of shape memory alloy (SMA) wire is tempered by conservative design guidelines set to mitigate complex factors such as functional fatigue (shakedown). In addition to stroke loss, shakedown...

...Hai-Jun Su; Hafez Tari In this paper, we study the type synthesis of wire flexures to achieve orthogonal motions by using a recently developed screw theory based design approach. For a given desired mobility pattern, our goal is to find a system of wire flexures that are simply connected...

...M. Sreekumar; T. Nagarajan; M. Singaperumal Large displacement static analysis of a fully compliant spatial mechanism is presented here. This mechanism is made up of a superelastic nitinol pipe as its compliant structural member and actuated by three shape memory alloy (SMA) wires. The coupled...

...Moshe Shoham A type of actuation used in ancient times, based on twisting wires, is reinvented in this paper. Twisting wires actuation was used long ago to pull heavy objects, but, to the best of the author’s knowledge, this investigation represents the first demonstration of its ability to achieve...
