Let's start with a little story about a boy who was paralyzed after a traffic accident a few years ago. His legs were completely unable to walk, but now, with the help of an electronic implant in his spine, he stood up again.
This miraculous spinal electronic implant, though only 6 centimeters long, can be installed in a patient's spine like a small computer, mimicking the brain's nerve signals by sending electrical impulses to muscles. The patient is able to regain control of the muscles. If the implanted electrodes were longer and larger, more muscle could be stimulated, and boys can now stand on their own for two hours and can walk more than a kilometer. In the future, you may be able to complete sports such as climbing and running.
The implant is only suitable for people with injuries above the lower thoracic spinal cord, so six centimeters of healthy spinal cord space needs to be left to place the implant. The R&D team plans to miniaturize the implanted computer for better control and convenience for more patients.
