An exemplary CNT-based actuator includes a first electrode, a second electrode opposite to the first electrode, and a CNT layer sandwiched between the first electrode and the second electrode. The CNT layer includes two opposite surfaces in contact with the first and the second electrodes respectively, and a plurality of CNTs substantially parallel to each other. The first electrode and the second electrode are configured for cooperatively creating therebetween an electric field with an electric field direction substantially parallel to the CNTs so as to adjust a thickness of the CNT layer, thereby moving the second electrode relative to the first electrode.
