The technology that was previously only available in science fiction is now being developed by French researchers.

The “semi-robot” implant can be attached to the spine to allow paralyzed patients to walk again. A micro-belt with electrodes can be placed along the spine while emitting electrical pulses and administration. These implants are as soft as real tissue, and the researchers say it can even be connected to the brain.

The sputum mouse that placed the implant only needed a few weeks of training to walk again. French researchers hope that the technology can be quickly applied to humans for clinical trials.

These small devices mimic the characteristics of living tissue and are capable of simultaneously delivering electrical pulses and administration. Researchers believe that the device can be placed in the human body for at least ten years.

Professor Stéphanie Lacour and Professor Grégoire Courtine stated that their e-Dura implants can be applied directly to the spinal cord without causing damage and inflammation.

The researchers tested the prototype of the device by applying the principle of recovery and reconstruction, which was tested on the rats by electrical stimulation and chemical simulation.

The experiment not only confirmed the biocompatibility of the implant, but also the device performed perfectly, allowing the mouse to regain its athletic ability.

The device can also be used to monitor electrical impulses from the brain in real time. Scientists can accurately capture the animal's intent of motion before converting to motion.

Implants developed by EPFL can be placed directly under the dura mater on the spinal cord.

The ductility and deformability of the implant are almost identical to the surrounding living tissue. This minimizes friction and inflammatory reactions. Within two months of implantation into the mouse, the e-Dura prototype caused neither damage nor rejection.

The R&D team stated that the development of e-Dura is a feat of engineering.

As flexible and flexible as living tissue, the device includes electrode elements that stimulate the injured part of the spinal cord. A silicon substrate overlying the separated gold electrode leads can provide stretch and ductility. The electrodes consist of a revolutionary combination of silicon and platinum particles. They are able to deform in any direction while ensuring the best conductivity.
