Abstract: A conductive and flexible carbon fiber according to the present disclosure includes a carbon fiber; a resin layer formed on the carbon fiber; and a metal plating layer formed on the resin layer. The resin layer of the carbon and flexible carbon fiber according to the present disclosure is uniformly coated on the carbon fiber, such that a breakage of the carbon fiber during the conductive carbon fiber production process may be prevented. In addition, the metal plating layer having the uniform thickness is plated on the resin layer having the uniform thickness, such that the electric conductivity of the carbon fiber may be improved and the flexibility of the carbon fiber may also be increased. In addition, a production process of the carbon and flexible carbon fiber according to the present disclosure is simplified, such that the production cost and time may be saved.

Abstract: Provided is a standalone Internet of things (IoT) gateway that can provide IoT services without going through a server comprising a connection mode determination unit which determines one of a first connection mode and a second connection mode, a first service performing unit which transmits status messages obtained from one or more IoT devices to a smart device of a user through a router or receives control commands for the IoT devices from the smart device of the user through the router and transmits the received control commands to the IoT devices and a second service performing unit which transmits the status messages obtained from the IoT devices to a management server through the router or receives the control commands for the IoT devices from the management server through the router and transmits the received control commands to the IoT devices.
