Electrically-heated flexible driver, applications thereof, and locking unit driven by driver

An environmentally-friendly electrically-heated flexible driver. The electrically-heated driver consists of a structure of dual layers, that is, a carbon nanotube and water-soluble polymer composite material layer and a carbon nanotube and silicon rubber composite material layer, and a great bending displacement and curvature can be obtained in low-pressure driving. The electrically-heated driver can be designed to obtain an intelligent material such as a pair of electrically-driven tweezers, an electrically-driven medicine spoon and an electrically-driven bionic tendon or ligament, and has a broad application prospect. A type of locking units driven by the flexible driver can also be manufactured according to the principle of the driver. The locking unit mainly consists of a support portion, a flexible driver and a locking buckle, and allows the flexible driver to perform bending motion under the driving of external energy, so as to achieve firm locking of the locking unit. The locking unit can be designed so as to be used in a locking apparatus in space capture, artificial intelligence and other fields, for example, the locking unit can be used to manufacture a flexible space capture and locking apparatus.
