Shape Memory Alloy Actuators Enable Compact, Silent Motion
Shape memory alloy (SMA) actuators use nickel-titanium (Nitinol) wires that contract when heated, returning to a pre-trained shape. They offer high force-to-weight ratio, silent operation, and design simplicity for aerospace, medical devices, and automotive applications.
2 FAQs:
How fast can SMA actuators cycle? 1–10 Hz with active cooling; slower without.
What is the typical lifespan? 1 million to 10 million cycles depending on strain.
