| Outline of Final Research Achievements |
In built-in cameras for smartphones, electromagnetic actuators with permanent magnets are used to drive the lens for image stabilization. The miniaturization of the electromagnetic actuators is required to minimize the built-in cameras. However, such actuators have reached the limit of miniaturization due to the limitation of micro magnetization of neodymium magnet. To solve this problem, in this study, micro magnetization method using laser assist heat for neodymium micro magnet as an alternative to pulse magnetization is developed.
