As an alternative actuator for mechanical oscillator, I found SMA wire actuators. SMA wire actuator is a linear actuator that has the similar function to the SCP actuators. I decided to test the practicability of SMA actuator as an actuator of the mechanical oscillator because there are some advantages to SMA wire actuators. One is a repeatability of its actuation. It may make the designing process of the mechanical oscillator easier. Another advantage is that it does not require any fabrication process. This property of the actuator can make the fabricatoin of the mechanical oscillator much easier. By this experiment, I found that SMA actuator can function like SCP actuator. However, it turned out that it has some problems to implement to the mechanical oscillator which SCP actuator also had.
