Create fake legs as true

A new study and invention by scientists from Vanderbilt University will be a useful solution to help disabled people get natural gait like normal people.

With this new method, handicapped people no longer have to keep their feet in the same way as conventional artificial legs are widely used today.

This device uses the latest advances and achievements of computer technology, can flexibly apply biological features as well as electronic control capabilities.

This is the first prosthetic leg that the knee and ankle joint operates in a coordinated manner. It is equipped with sensors to track user movements . Besides, it also uses programmed microprocessors to predict what users are trying to do and control this device in the most convenient way for movement.

'An artificial leg is always my obsession and guilt. It makes it very difficult for me to move. However, the artificial leg, studied by scientists at Vanderbilt University, is the exact opposite. When operating, it's completely different from the current prosthetic device I'm using , 'said Craig Hutto, a 23-year-old from the United States who has been experimenting with the new invention.

The biological leg using these electronic control techniques is the result of a 7-year study by scientists and engineers from the Smart Mechatronics Center of Vanderbilt University led by the Church. Professor Michael Goldfarb leads. The project was originally funded by the Science Foundation and the National Institutes of Health. This design has been the patented University and exclusively distributed by Freedom Innovations, a leading company specializing in the production of American orthopedic engineering equipment.

'With this latest model, we have confirmed the previous hypotheses that technology has evolved to create prosthetic legs with knee and ankle joints that work together in harmony. Our equipment has demonstrated the progress of current science when integrating both people and computers , 'Goldfarb stressed.

This fake leg is designed to cater to everyday activities. It makes it easier for people with disabilities to walk, stand, sit, walk up or down stairs and ramps. Research results have shown that people using this new device have about 25% faster travel speeds than previous prosthetic devices.

Advances in current technology have facilitated Vanderbilt University engineers to build a device that weighs about 9 pounds, much lighter than current prosthetics, and can operate. continuous for 3 days, equivalent to 13-14 km per charge. At the same time, this device also significantly reduces the amount of noise emitted.

One of the outstanding features that engineers have retrofitted to this new device is its ability to resist tripping thanks to a biosensor.

To incorporate these advances, scientists have to revise the hardware design of the legs up to 15 times.

Currently, scientists from the Intelligent Mechatronics Center are also in the process of researching a new project with the development of a similar prosthetic arm and an external skeleton to help support physical therapy. therapy.
