ZINC OXIDE NANO-WIRE BASED ACTUATOR, LENS MODULE USING SAME AND CAMERA MODULE USING SAME

摘要

An exemplary zinc oxide nano-wire based actuator includes a first electrode, a second electrode opposite to the first electrode, and a zinc oxide nano-wire layer sandwiched between the first electrode and the second electrode. The zinc oxide nano-wire layer includes two opposite surfaces in contact with the first and the second electrodes respectively, and a plurality of zinc oxide nano-wires 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 zinc oxide nano-wires so as to adjust a thickness of the zinc oxide nano-wire layer, thereby moving the second electrode relative to the first electrode.
