Abstract: A Bidirectional, Linear and Binary, Segmented Antagonistic Servomechanism-based Shape Memory Alloy (SMA) Actuator  comprising a main stroke transmitting lever (11 or 18) and a plurality of part-modules (15A or 15B) disposed in a closely spaced  arrangement and adapted to undergo a reciprocal translation in a first direction. wherein, the part-modules comprising a plurality of  segments having SMA elements (12). The invention provides two configurations arranged in 'straight' and 'cross' configurations of  the SMA elements in the part-modules. Further above configuration are arranged in a tight close space however, the 'cross'  configuration provides additional 40% compactness. The configurations comprise a 'S-type long tail' or 'flipped F-type long tail'  main stroke transmitting lever and plurality of 'straight' or 'cross' configurations part modules, respectively. The novel embodiment  can be utilized for micro-positioning of 3D printer filament extruder head, linear and angular displacement applications such as  robotic, prosthesis, bi-stable position control, latching-unlatching systems, and other wide engineering applications.
Startup Options: The novel embodiment  can be utilized for micro-positioning of 3D printer filament extruder head, linear and angular displacement applications such as  robotic, prosthesis, bi-stable position control, latching-unlatching systems, and other wide engineering applications.
