我们通过在弹性铰链处折叠来制作空间微结构。然而，微折叠导致困难，例如难以接近、耗时的任务以及对结构的损坏。在这份报告中，我们建议安装微致动器的微结构折叠出一个平面结构。致动器基于洛伦兹力，其作用于磁场中的电流。该致动器可以简单地通过使用外部磁场来制造。洛仑兹力的振幅可以由电流或磁场控制。此外，力的方向可以由场的方向控制。
We've made a spatial micro-structure by folding at elastic hinges. However, the micro-folding causes the difficulties, e.g. hard access, a time-consuming task, and damage to the structure. In this report, we propose installing micro-actuators on a microstructure to fold it out of a planar structure. The actuator is based on the Lorentz force, which acts on a current in a magnetic field. This actuator can be made simply by using an external magnetic field. The amplitude of the Lorentz force can be controlled by either the current or the magnetic field. Also, the direction of the force can be controlled by the direction of the field.
