A movable sensor device includes a laminate body in which a micromechanical acting layer having a movable sensor structure and a coating layer coated on the micromechanical acting layer is successively laminated on a substrate. One implementation is a lotion-containing two handled device that interlocks together to form a sealed unit. Therefore, the passive fan may be rotated without needing a power supply, and the passive itself will not generate high temperature and high heat, thereby further increasing the cooling and heat dissipating efficiency thereof on a heat emitting member.
