Abstract

Shape Memory Alloy (SMA) is a special alloy that can change its shape due to temperature that imposed to the alloy. This phenomenon can be applied by using current voltage as exchange for the temperature. The unique behavior of SMA makes it suitable as an actuator. Its small size allows it to compete with other actuators such as pneumatic actuator, hydraulic actuator, and motor actuator. SMA actuators nowadays are widely used especially in robotic field, medical field, also have been applied in aircraft industry. SMA also applicable in automotive industry, it can be used in many parts in the vehicle that are need to using actuator or can replace the existing actuator with the SMA actuator. For the automotive louver, the application of it is by using finger and some more advances are made by using motor actuator to adjusting the louver. In this project, an invention is applied by changing the mechanism by using a button to adjusting the position of the aircond louver, and the result is satisfied. According to SMA’s size, it can suit with the louver to create the SMA louver actuator. This great combination may be a new invention, but researches have been made before and the suitability is infallibility. Many design of SMA louver actuator have been made, and the best design is defined based on the value of advantages among all designs.
