Technology helps people lose their legs dancing and swim like fish

Now people have created parts to replace. It is the result of bionic inventions (fake biology), bringing a better life to patients.

The tail helps people lose their swimming legs like fish

Scientists have created a 'tail' that helps Nadya Vessey, a woman in Auckland, New Zealand, can swim like fish. Nadya Vessey has a congenital disease and is forced to remove his leg and use artificial legs.

Nadya frequented the swimming pool and one day, happened to meet a stranger when he saw her wearing a prosthetic limb, wondering why she still went swimming in such a condition.

Scientists have created a 'tail' that helps Nadya Vessey, a woman in Auckland, New Zealand, can swim like fish.

Nadya Vessey joked that he was a mermaid. From the above situation Nadya contacted the Weta Workshop prosthetic workshop, a company specializing in cinematography techniques, to order the tail. Thanks to that, Nadya swam freely under the tank like a mermaid.

This bio-fake tail allows Vessey to swim easily and flexibly like legendary creatures. It has a complete structure with both polycarbonate fin and tail layers, the finned layer is digitally printed, so it is difficult to detect.

Although Vessey has no legs, Vessey still walks normally and swims. Even thanks to the bionic tail, Vessey can participate in triathlon competition (3 combined courses).

Bionic ankle

According to Hugh Herr, director of the Biomechatronics Group of the Massachusetts Institute of Technology (USA), biomedical technology is developing rapidly, many physical or disability-related diseases will soon be overcome. Many people with disabilities who have been rehabilitated are like a healthy person.

The case of dancer Adrianne Haslet-Davis is an example. Once a professional dancer, unfortunately Adrianne lost a leg in the Boston Marathon bombing.

Soon after the accident, Adrianne was quickly taken to an ambulance to Boston medical center. On the car, Adrianne tried to tell the nurse that she was a dancer, trying to put her legs back, but to ensure her life, the doctors were forced to remove half of her lower legs. left.

Thanks to her biological ankle, Adrianne Haslet-Davis still danced normally after being cut off.

Hugh Herr, who lost his leg in a climbing accident, was the one who designed and created an artificial ankle to restore Adrianne's dancing ability.

Hugh Herr and his colleagues provided prosthetics for over 90 people, with customized versions of bionic ankles.

Artificial knee

Advances in technology have made it easier for people with disabilities to travel like American schoolgirl Hailey Daniswicz, who lost her lower left leg due to bone cancer in 2005. Hailey Daniswicz is training to use it. This bio-fake knee.

According to Levi Hargrove, an expert at the Rehabilitation Institute of Bionic Chicago Medical Center (USA), to help Daniswicz go, scientists have chosen to integrate people and machines. Which uses electrical signals and computer software to control the new robot leg.

The electrodes are attached to 9 different muscle parts of Daniswicz's thigh, acting as antennas, receiving electrical signals sent from neurons to muscles. These electrical signals are emitted according to certain patterns depending on Daniswicz's intention to move.

After a while, computers can identify these patterns to 'guess' the patient's intention to move. Daniswicz and three other people involved in the test not only moved their legs and bent their knees but also controlled their ankles with bionic knees.

If the project is successful, it is hoped that bionic knees and limbs will create a revolution in the field of artificial limbs, helping to improve the quality of life for the group of people who suffer diseases or accidents.

Biological teeth

As predicted, the ability to regenerate teeth and prevent cavities by bionic technology will be exciting in the future. Accordingly, dentists will use biological alternatives to solve the problem of tooth decay.

Dr. Ana Angelova Volponi, an American biologist, said that the research on creating biological teeth is one of the key discoveries in the field of dentistry, giving birth to new generation of teeth by using cells. Adult gum root.

In particular, thanks to 3D printing technology, people will produce new generation of teeth, with high compatibility, not eliminated, helping users feel more comfortable than traditional dental implant.
