摘要
PURPOSE: A shape memory alloy double spring and a shape memory alloy actuator having the same are provided to secure high output of a shape memory alloy actuator because the deformation amount per unit length of a shape memory alloy double spring is greater than that of the conventional spring.;CONSTITUTION: A shape memory alloy actuator comprises a shape memory alloy double spring(10), a power unit, and an output unit. The shape memory alloy double spring has a double spring structure in which a primary spring formed by spirally coiling a wire is spirally coiled again. The power unit thermal elastically transforms the shape memory alloy double spring by applying power to the shape memory alloy double spring. The output unit is connected to an end of the shape memory alloy double spring and outputs the deformation amount of the shape memory alloy double spring in a desired exercise form.;COPYRIGHT KIPO 2012
