Adaptive reversible composite-based shape memory alloy soft actuators

This research demonstrates how a combination of two-way shape memory alloy (SMA), low-temperature liquid epoxy cure composites, and fibre reinforced plastic (FRP) may be utilised to create novel reversible actuator with built driven functionality. The novelty this work is that the can reverse its original mounted on different customized structures. strategy based knowledge SMA wires manufacturing principle underlying composite structure, as well experiments see soft SMA-FRP programmed bend. folding mechanism studied in terms fabrication factors such training strong interfacial bonding between resin, which influence programming process change. are trained using pre-straining method programme SMAs. technique has been used assemble bond reliability enhance interface's thermal behaviour. elements directly inserted into FRP strips resin an adhesive, resulting dynamic hybrid composites. module actuated electrical board current value 3 6 A. robustness, controllability, mechanical properties, 500 life cycles tested. Results indicate bending angle 58° 30 mm deflection 7 s after actuating module. Also, 3D printing print gripper inspired by human fingers structure lift various weights. actuator’s performance reliable grasping objects shapes.
