The prosthesis is controlled by brain signals

15.08.2013

Easton LaChappelle, an American from California, made a breakthrough in the field of creating prostheses based on modern technologies. He developed a prosthetic hand that costs many times less than similar analogues, and taught him to perceive brain signals.

The prosthesis, designed by Easton, is valued at less than $400. Its main frame is 3D printed, which significantly reduced the cost of production, but at the same time did not affect strength. According to the inventor himself, his creation is very strong - each of the five fingers can hold weight up to 22 kilograms. Indeed, such a hand does not hold strength.

The artificial fingers of the prosthesis are set in motion by special servo drives, thanks to which the maximum natural position of the hand is achieved and the possibility of using it to replace the lost limb. The prosthesis, as mentioned above, is literally controlled by the brain - it is connected to it using a wireless EEG system that reads special brain signals, interprets them and transmits them to an artificial arm.

Many organizations are actively interested in the invention of a 17-year-old teenager, as it can significantly reduce the cost of producing prostheses and reduce the price of them themselves. The NASA space organization has been the fastest in terms of responding to the emergence of a new genius-nugget - Easton is already working in it, but so far as an intern. According to him, he gathered all the information necessary to create a tablet from books and the Internet, without asking for help from specialists.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

First sight 10.04.2000

Sixty-two-year-old American Jerry N. is able to read the house number on the wall, does not bump into objects, watches TV, knows how to surf the Internet, does not miss hanging his hat on a nail ... This would not be surprising if he had not lost his sight over 20 years ago.

The fact is that Jerry N. received an artificial vision system, on which a group of engineers led by R. Dobell worked for more than 30 years. A miniature television camera is mounted on the glasses of the former blind man, the signals from which are fed into a computer mounted on his belt. After processing, these signals go directly to the brain, to the visual cortex, through 68 platinum electrodes implanted there. Artificial vision is much weaker than natural, but still allows you to lead an almost normal life.'

Serial production of such "artificial eyes" may begin this year.
