In this work, an actively tunable optical metadevice is proposed to realize multifunctional application by integrating self-assembly electrothermal actuator (ETA) and magnetic metamaterial. The released frame of ETA can control the deformed height metamaterial plate then provide high robustness. By driving external electromagnetic field, actuated rotated a force manipulate incident response. transmission intensities be gradually increased characterize "on" "off" states. Along with inputs light source results could output time-difference signal carry digital information in further logic operation. Such actuation method provides ideal platform for large tilt angle displacement. MEMS-based strategy open avenue communication, 3D imaging, switching applications.
