2D materials exposed to light could transform into 3D objects
A research team led by North Carolina State University (NC State) is developing methods to create 2D materials capable of folding themselves into 3D objects when exposed to light.
The work, funded by a grant worth approximately $1.76m (£1.11m) over four years from the US National Science Foundation (NSF), is inspired by origami and is claimed to have a broad range of potential applications.
‘We’re pulling together a diverse team of designers, engineers and mathematicians to advance our understanding of how to manipulate photoresponsive materials,’ said Dr Jan Genzer, Celanese professor of chemical and biomolecular engineering at NC State and the primary investigator under the NSF grant. ‘Ultimately, we hope to develop new techniques that have applications ranging from electronics to high-volume manufacturing to the delivery of humanitarian relief.’
According to a statement, the researchers plan to use experiments and computational models to evaluate the folding process in order to develop new multi-functional 3D structures that can form rapidly while retaining precise control over their shape.
Because the patterns will be on 2D materials, the process should be compatible with high-throughput patterning techniques, such as roll-to-roll patterning used in electronics manufacturing.
Potential applications include the development of unfoldable air foils that could be used for airdrops of humanitarian supplies with greater precision; the hands-free assembly of electronics in a ‘clean’ environment; or various packaging and manufacturing processes.
The research effort builds on earlier research from NC State, which detailed a simple way to convert 2D patterns into 3D objects using only light. In that work, the researcher ran pre-stressed plastic sheets through a conventional inkjet printer to print bold black lines on the material.
The material was then cut into a desired pattern and placed under an infrared light, such as a heat lamp. Because the bold black lines absorbed more energy than the rest of the material, the plastic contracted — creating a hinge that folded the sheets into 3D shapes.

/ About us
Founded by Russian entrepreneur Dmitry Itskov in February 2011 with the participation of leading Russian specialists in the field of neural interfaces, robotics, artificial organs and systems.
The main goals of the 2045 Initiative: the creation and realization of a new strategy for the development of humanity which meets global civilization challenges; the creation of optimale conditions promoting the spiritual enlightenment of humanity; and the realization of a new futuristic reality based on 5 principles: high spirituality, high culture, high ethics, high science and high technologies.
The main science mega-project of the 2045 Initiative aims to create technologies enabling the transfer of a individual’s personality to a more advanced non-biological carrier, and extending life, including to the point of immortality. We devote particular attention to enabling the fullest possible dialogue between the world’s major spiritual traditions, science and society.
A large-scale transformation of humanity, comparable to some of the major spiritual and sci-tech revolutions in history, will require a new strategy. We believe this to be necessary to overcome existing crises, which threaten our planetary habitat and the continued existence of humanity as a species. With the 2045 Initiative, we hope to realize a new strategy for humanity's development, and in so doing, create a more productive, fulfilling, and satisfying future.
The "2045" team is working towards creating an international research center where leading scientists will be engaged in research and development in the fields of anthropomorphic robotics, living systems modeling and brain and consciousness modeling with the goal of transferring one’s individual consciousness to an artificial carrier and achieving cybernetic immortality.
An annual congress "The Global Future 2045" is organized by the Initiative to give platform for discussing mankind's evolutionary strategy based on technologies of cybernetic immortality as well as the possible impact of such technologies on global society, politics and economies of the future.
Future prospects of "2045" Initiative for society
2015-2020
The emergence and widespread use of affordable android "avatars" controlled by a "brain-computer" interface. Coupled with related technologies “avatars’ will give people a number of new features: ability to work in dangerous environments, perform rescue operations, travel in extreme situations etc.
Avatar components will be used in medicine for the rehabilitation of fully or partially disabled patients giving them prosthetic limbs or recover lost senses.
2020-2025
Creation of an autonomous life-support system for the human brain linked to a robot, ‘avatar’, will save people whose body is completely worn out or irreversibly damaged. Any patient with an intact brain will be able to return to a fully functioning bodily life. Such technologies will greatly enlarge the possibility of hybrid bio-electronic devices, thus creating a new IT revolution and will make all kinds of superimpositions of electronic and biological systems possible.
2030-2035
Creation of a computer model of the brain and human consciousness with the subsequent development of means to transfer individual consciousness onto an artificial carrier. This development will profoundly change the world, it will not only give everyone the possibility of cybernetic immortality but will also create a friendly artificial intelligence, expand human capabilities and provide opportunities for ordinary people to restore or modify their own brain multiple times. The final result at this stage can be a real revolution in the understanding of human nature that will completely change the human and technical prospects for humanity.
2045
This is the time when substance-independent minds will receive new bodies with capacities far exceeding those of ordinary humans. A new era for humanity will arrive! Changes will occur in all spheres of human activity – energy generation, transportation, politics, medicine, psychology, sciences, and so on.
Today it is hard to imagine a future when bodies consisting of nanorobots will become affordable and capable of taking any form. It is also hard to imagine body holograms featuring controlled matter. One thing is clear however: humanity, for the first time in its history, will make a fully managed evolutionary transition and eventually become a new species. Moreover, prerequisites for a large-scale expansion into outer space will be created as well.
