| Outline of Final Research Achievements |
I experimented in order to apply an artificial muscle to a orthodontic treatment. As an artificial muscle material, I experimented by choosing a coil shape memory alloy actuator. I applied the electric current controlled by Pulse Width Modulation. Tension was become to 45.8gf when the electric current was adjusted to the voltage 5.7V and the average voltage 0.62V. Tension was 44.7gf (97.7%) in 4 hours after an experiment start.
The results of this study suggest that when adjusting the electric current to apply, it proved that for a long time almost constant force appears. From this, if the electric current which apply to an artificial muscle is turned on or turned off, a force will turn into continuous force, intermittent force, and interrupted force.
