Abstract: An electrically-actuated artificial muscle fiber with bidirectional linear strain and a preparation method thereof are provided. The artificial muscle fiber includes a fiber matrix, electrode layers and insulating layers. The artificial muscle fiber takes the fiber matrix as a skeleton, upper and lower layers of the fiber matrix are covered with one electrode layer respectively, and one insulating layer is covered on a surface of each of electrode layers. A helical fiber body is formed by winding. Finally, the artificial muscle fiber is formed through packaging, where metal wires are taken as leads and respectively connected to upper and lower layers of electrodes.

Abstract: A thermally-driven full-ocean-depth lens wiping device and a method. The device includes a wiper hingedly mounted on a housing, a shape memory alloy wire mounted on the housing and configured to connect and drive the wiper to perform a wiping motion, and a fixing component configured to position and arrange the shape memory alloy wire, and further includes the housing mounted on a full-ocean-depth lens and a waterproof connector electrically connected to the shape memory alloy wire; in the method, the shape memory alloy wire is electrically heated to be extended and contracted, thereby pulling the wiper to rotate, and wiping of the lens is completed.
