The new bionic knee developed by MIT researchers is designed to integrate seamlessly with a user’s muscle and bone, allowing individuals with above-the-knee amputations to walk faster and navigate obstacles more effectively. Led by Hugh Herr and his team, the technology utilizes a method called agonist-antagonist myoneuronal interface (AMI), which extracts neural signals to control prosthetic limbs, significantly improving the naturalness of movement.
A clinical study demonstrated the effectiveness of the knee, with two participants showing enhanced performance in tasks such as stair climbing and overall comfort compared to those using conventional prosthetics. By inserting a titanium rod into the residual femur, the researchers achieved better mechanical control and weight support. This technology, which could redefine the experience of prosthesis users, emphasizes integration with the body’s systems for a more natural feel. Herr anticipates that further trials are necessary for FDA approval, which he believes could take around five years.
