Tractor beams of science fiction becoming a reality

The tractor beam, a staple of science fiction including "Star Wars" and "Star Trek" that is employed to grab spaceships and other things remotely, is entering the realm of reality.

Researchers on Tuesday said they have developed a tractor beam that uses high-amplitude sound waves to levitate, move and rotate small objects without making contact with them. They envisioned medical and other applications for the device.

"As a mechanical wave, sound can exert significant forces on objects. Just remember the last time you were in a concert and your chest was vibrating with the music," said study lead author Asier Marzo of Britain's University of Bristol and Spain's Public University of Navarre.

Marzo said this sonic tractor beam has manipulated objects up to about one-seventh of an inch (4 mm) in diameter and can control the position and orientation of the levitated objects.

The tractor beam uses ultrasound at a frequency of 40 kilohertz. People can hear only below 20 kilohertz.

The researchers used sound waves from 64 miniature loudspeakers called transducers to create what they called "acoustic holograms" to control an object without touching it. These waves took the form of tweezers to lift an object, a vortex to hold a levitating object in place and a cage to surrounds an object and hold it in place.

"A simple wave will just push the particle in the direction of propagation. However, multiple waves will interfere with each other and create complex, acoustic 3D shapes that exert forces from all directions and keep the particle in place," Marzo said.

Marzo said the largest object moved using the device was a 4 mm bead made of a light plastic called polystyrene.

"With special high-power transducers it would be possible to levitate even steel balls," Marzo said.

Marzo described possible medical applications.

"Sound cannot travel through the void of space but it can do it through water or human tissue. This potentially enables the manipulation of clots, kidney stones, drug capsules, microsurgical instruments or cells inside our body without any incision," Marzo said.

More powerful sonic tractor beams capable of levitating bigger objects from greater distances could control objects floating adrift in zero-gravity environments like inside the International Space Station, Marzo said.

The research, which also involved researchers at Sussex University and a British company called Ultrahaptics, was published in the journal Nature Communications.

/ 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.
