A new invention enables amputees to control a robotic arm with their minds, making mind reading possible

Through the use of electronics and AI, a research team from the University of Minnesota has made mind-reading possible.

Amputees who are unable to use their muscles to control a robotic arm can now do so thanks to a device developed by researchers at the University of Minnesota Twin Cities. Compared to earlier technologies, this one is more accurate and less invasive.

Nowadays, the majority of commercially available prosthetic limbs are operated by the shoulders or chest via a cable and harness system. The native limb above the prosthetic that the patient is using is monitored by sensors in more advanced models. However, both techniques can be challenging for amputees to learn to utilize and occasionally are useless.

A tiny, implanted device that links to a person’s peripheral nerve in the arm has been created by the University of Minnesota’s Department of Biomedical Engineering with assistance from commercial partners. The device can detect and analyze brain impulses when used in conjunction with a robotic arm and an artificial intelligence computer, allowing amputees of the upper limb to operate the arm solely with their thoughts.

The most recent study by the researchers was released in the peer-reviewed scientific publication Journal of Neural Engineering, which focuses on the multidisciplinary subject of neural engineering.

Jules Anh Tuan Nguyen, a postdoctoral researcher and University of Minnesota Twin Cities biomedical engineering Ph.D. graduate, said of the system, “It’s a lot more intuitive than any commercial system out there.” “With previous commercial prosthetic systems, amputees don’t genuinely consider moving a finger when they wish to. Since the system detects arm muscles, they are attempting to contract those muscles. These systems need a lot of training and practice as a result. Because we immediately read the nerve signal with our technology, it is aware of the patient’s purpose. All they need to do to move a finger is think about moving that finger.

Nguyen has been conducting this study with Zhi Yang, an associate professor in the University of Minnesota’s Department of Biomedical Engineering, for about ten years. Nguyen was a crucial figure in the creation of the neural chip technology.

Yang was approached in 2012 about developing a nerve implant that could help amputees by Edward Keefer, a business neuroscientist and CEO of Nerves, Incorporated. The duo completed numerous successful clinical trials with actual amputees after receiving financing from the Defense Advanced Research Projects Agency (DARPA) of the United States government.

In order to commercialize the technology, the researchers also collaborated with the University of Minnesota Technology Commercialization office to create a firm named Fasikl, which is a play on the word “fascicle,” which describes a bundle of nerve fibers.

It’s crucial, according to Nguyen, that we have an impact on actual people and eventually enhance the lives of patients. “Creating new technology is exciting, but if you’re just conducting research in a lab, no one will really be affected. We wish to participate in clinical studies at the University of Minnesota because of this. I’ve had the honor of dealing with multiple human patients over the past three or four years. When I am able to help someone move their finger or do something they previously believed to be impossible, I might become very emotional.
