Abstract: Brain-machine intelligence integrates ubiquitous intelligence technology and regulation technology, enabling bidirectional interaction and regulation between the human brain and the external environment, thereby enhancing human capabilities in behavior, cognition, consciousness, and emotion. First, the concepts and relationships of smart sensing, regulation, and brain-machine intelligence are introduced. Next, a macro description of the technical framework of brain-machine intelligence system is provided, including the sensing layer, regulation layer, algorithm layer, and Application layer. Finally, typical work on the brain-machine intelligence system is presented.
