Imagine being able to open jars, zip up your jacket, and use a screwdriver—all with a prosthetic hand.
This is now a reality for individuals thanks to an innovative, magnetically controlled bionic limb.
A Breakthrough in Prosthetic Technology
The groundbreaking bionic hand, developed by researchers at the BioRobotics Institute in Italy, is the first of its kind.
It features tiny implanted magnets in the forearm that respond to the user’s brain signals, allowing for precise control of the prosthetic’s movements.
The device translates signals from six magnets embedded in the residual arm into intricate and natural movements.
Success Story of Daniel
Daniel, a 34-year-old who lost his left hand in 2022, was among the first to test this advanced prosthetic.
After using the bionic hand for six weeks, he described the experience as feeling “like moving my own hand.”
The prosthetic’s success was evident as Daniel could perform daily tasks like opening jars, using tools, and even handling delicate objects with finesse.
How It Works
The prosthetic functions by placing small magnets within the muscles of the forearm that once controlled the hand.
These magnets detect muscle movements, sending magnetic signals to a computer program that then translates them into precise movements of the robotic hand.
This technology allows for fine motor skills comparable to those of a natural hand.
Insights from Experts
Professor Christian Cipriani of the BioRobotics Institute explains that the forearm contains 20 muscles, many of which are involved in hand movements.
Even after amputation, these residual muscles continue to respond to brain signals, making this new technology possible.
Daniel, selected for the study due to his persistent sense of his lost hand, had six magnets implanted in April 2023.
The results exceeded all expectations, enabling him to perform a wide range of activities with the prosthetic.
Future Prospects
The trial’s results, published in Science Robotics, mark a significant advancement in prosthetic technology.
Despite the exciting progress, the NHS currently does not fund this advanced bionic arm.
However, NHS England announced in November 2022 that many amputees would soon have access to similar bionic arms capable of mimicking real hand movements.
The Evolution of Prosthetics
Traditional NHS prosthetics were limited to basic models with simple open-and-close functions or cosmetic designs with no practical use.
In contrast, new bionic arms represent a major leap forward.
Recent developments include a “brain-powered” bionic arm that integrates directly with the patient’s bones and nerves.
This technology, pioneered by Prensilia, an Italian prosthetics firm, eliminates the need for uncomfortable sockets and offers a more seamless connection between the prosthetic and the user.
What’s Next?
The future looks promising for bionic prosthetics, with options available for individuals as young as nine.
As technology advances, these devices—ranging from £25,000 to £80,000—are becoming increasingly accessible, providing more people with the opportunity to regain functionality and improve their quality of life.
