Sensor technology is expected to help amputees recover more activity functions

Abstract: mechanical prostheses can detect the electrical signals sent by the user's spinal cord motor neurons, making the control of prostheses more flexible, which is equivalent to controlling prostheses with ideas

an international team released a new report that with the help of the sensor technology they developed, the mechanical prosthesis can detect the electrical signals sent by the user's spinal cord motor neurons, making the control of the prosthesis more flexible, which is equivalent to controlling the prosthesis with ideas. Relevant technologies are expected to help amputees recover more motor functions

at present, most mechanical prosthetic products on the market rely on users to twitch the muscles of their shoulders or arms. This control method has poor user experience and limited functions, and can only perform oneortwo simple grasp action commands

according to the paper published in the new issue of nature biomedical engineering in the UK, researchers from scientific research institutions in the UK, the United States, Austria and other countries have jointly developed a new sensor to enable the mechanical prosthesis to directly detect the electrical signals from spinal cord motor neurons. Compared with the control method based solely on muscle twitch, such control can be more accurate and the actions that can be completed are more complex, The practicality of mechanical prosthetics has been improved

After the 910s, the team asked six volunteers to participate in the test. They were either amputated from the shoulder or above the elbow. In order to better carry out the test, the volunteers received repeated experimental operations on many parameters, such as the particle size of salt, the compounding method and proportion, the printing temperature, the printing rate, and so on. Part of their peripheral nervous system was readjusted and connected to healthy muscles. After a certain training, volunteers only need to imagine moving their arms to do different actions in their minds. The sensors on the prosthesis can receive electrical signals and analyze them, so as to send instructions for manipulation, complete the actions of moving the elbow joint of the prosthesis, swinging the wrist of the prosthesis, opening and closing the palm, and realize most of the basic functions of the real arm

at this time, Dario farina, a professor at Imperial College of technology and one of the authors of the report, said that the new technology focuses on the nervous system rather than muscles, which means that the relevant signals can be detected and analyzed more clearly by using sensors, which can make the use of mechanical prostheses closer to intuitive control, and will be more useful to the disabled

in the next step, the team predicts that China will promote the development of Mongolia's processing industry by jointly building and operating saiyinshanda Industrial Park, and will conduct a wider range of clinical tests on this new mechanical prosthesis. After continuous improvement, this kind of product is expected to enter the market in the next three years
