Huake experts developed flexible electronic "printer" computer monitors that have become as soft as newspapers and can be folded into a backpack. This idea may be realized through the printing technology of flexible electronic devices in the next few years. It was learned yesterday that the flexible electronic printing device developed by the project team of Huang Yongan, associate professor of the School of Mechanical Science and Engineering, Huazhong University of Science and Technology, will hand over the finished product this month.

At the 42nd International Exhibition of Inventions in Geneva, Switzerland in April, the "Flexible Electronic Device Printing Technology and Equipment" won a gold award. The flexible electronic device jet printing manufacturing technology is an emerging electronic technology that manufactures electronic devices on flexible, malleable plastic or thin metal substrates, and has the advantages of being bendable, malleable, and controllable physical life.

After nearly 5 years of research, the team of Huang Yongan has taken electrohydrodynamic printing as the core to achieve non-contact, pressure-free, and printing-free printing and copying. This technology does not change the properties of flexible materials, the manufacturing process is simple, and is not affected by the area and shape of electronic devices. While improving the material utilization rate, it can also reduce environmental pollution.

This technology can realize automatic overprinting of multi-layer electronic structures, real-time observation of printed patterns, and intelligent spray printing of flexible electronic devices. "It looks like a printer, and it can achieve the efficient manufacture of large-area flexible electronic devices like printing newspapers," Huang Yongan said.

The team of Huang Yongan has completed the research of process principles and the development of manufacturing equipment, and the realization of intelligent printing equipment for flexible electronic devices has become the focus of the next research. In addition to being widely used in flexible electronics manufacturing, this technology can also be extended to bioprinting and material preparation, as well as device manufacturing in the fields of information, energy, and medical treatment.

Huang Yongan said that he hopes that the manufacturing cost of flexible electronic devices such as electronic display screens will be greatly reduced in the future. Just like we print documents now, we can throw them into the trash can and realize the printing and manufacturing of disposable and disposable electronic devices.
