Abstract
A moveable assembly includes a frame, resilient suspension arms made of carbon nanotube bundles, and a moveable member. The frame is disposed around the moveable member. Each of the resilient suspension arms includes a first end fixed to the frame, and a second end connected to the moveable member. The resilient suspension arms are centro-symmetrically arranged relative to the moveable member such that the moveable member is capable of stably moving along a predetermined direction driven by an external force.
