Shape Memory Alloy - SMA Actuator

By using shape memory alloys in the drive mechanism, we achieve miniaturization, energy saving, and noise reduction of the product!

By using actuators (drive devices and circuits) made of shape memory alloys, it is possible to achieve miniaturization, energy saving, and noise reduction of products. Shape memory alloys (SMA) are unique metals that can return to their original memorized shape when they reach a specific temperature. Utilizing this property, they can be activated by sensing an increase in the surrounding temperature of liquids or gases, or by being heated through electric current. Using actuators made of shape memory alloys allows for the miniaturization, energy saving, and noise reduction of products. There is no need for complex mechanisms; instead, the expansion and contraction of SMA springs and wires that respond to temperature can be utilized to replace traditional actuators with a powerful, yet simple, more compact, and stable mechanism. 【Features】 ○ Miniaturization (the size and weight of the actuator can be reduced due to a simple mechanism) ○ Reduction in material costs (it is possible to significantly decrease the number of parts) ○ Noise reduction (no noise generated from drive mechanisms such as motor sounds)
