Bionic Limbs

About

Bionic limbs are advanced prosthetic devices that utilize electronic signals from muscles and nerves to provide intuitive control and sensory feedback. They establish an interface between the biological residuum and electronic components, offering motor control and sensory feedback. These limbs can be categorized into three main types: nerve-transferred muscle interfacing, direct muscle interfacing, and direct nerve interfacing. Targeted muscular reinnervation (TMR) involves transferring nerves to available muscles, enhancing control. Direct muscle interfacing uses intramuscular implants to capture muscle contractions, while direct nerve interfacing employs implantable electrodes for nerve signals. Bionic limbs improve sensation, reintegration, and controllability, making them more natural extensions of the body. Recent advancements include mind-controlled limbs that integrate with the nervous system, allowing users to command movements with less lag. Surgical techniques like AMI (agonist-antagonist myoneural interface) surgery enhance neural control, enabling a more natural gait. These technologies are transforming lives by offering better mobility and functionality, bridging the gap between prosthetics and natural limbs. Despite advancements, challenges remain, including the need for fully implantable solutions to reduce infection risks and ensure long-term safety.
