Description
Technical Field
The invention relates to the field of intelligent steering wheels, in particular to a graphene electrode intelligent steering wheel system and a preparation method thereof.
Background
According to research, the causes of traffic accidents include non-trivial human factors for drivers, and up to 30% of accidents are caused by fatigue driving. If the vital sign information of the driver in the driving process can be collected in real time and the collected information is analyzed and predicted, early warning can be carried out in advance, and the risk avoiding effect is achieved.
The existing steering wheel cannot detect the heart rate, electrocardio and other vital sign conditions of a driver when the driver drives an automobile. When a driver is in fatigue driving or has sudden diseases, the driver cannot carry out timely detection and feedback, and serious traffic accidents are easily caused. It is therefore desirable to design an intelligent steering wheel system.
Graphene is a novel two-dimensional carbon nanomaterial with a single-layer sheet structure composed of carbon atoms, and has a larger specific surface area and higher chemical stability than Carbon Nanotubes (CNTs) and fullerenes (C60). Graphene is not only the thinnest of the known materials, but is also very strong and rigid, as a simple substance, it transports electrons faster at room temperature than known conductors. Graphene has attracted considerable attention in the field of material research by virtue of its excellent electrical, mechanical and thermal properties.
In the last decade, extensive research has been conducted on graphene-based nanomaterials due to their unique physical and chemical properties, and through synthesis and engineering design, graphene can have a porous and three-dimensional (3D) structure, enabling its wide application from composite fillers to energy storage devices. Although a great advance, the existing porous graphene synthesis methods require high temperature processing or multi-step chemical synthesis routes, thereby weakening the commercial potential of their widespread use. Therefore, direct synthesis, especially patterning of graphene-based nanomaterials, in scalable processes remains an important goal in the art to realize industrial micro energy storage devices. Current methods of preparing graphene-based electronic materials have many limitations in terms of manufacturing efficiency and electrical properties. Therefore, there is a need for a more efficient method of preparing graphene-based electronic materials and its application to steering wheels for monitoring the physical state of drivers.
