1. Magnets improve the mobility of prosthetic limbs.

Finding ways to make prosthetics feel as natural as possible has been a challenge for many decades. Finally, a group of researchers is now developing a way to provide a much more precise movement and control of prosthetic limbs. MIT’s Media Lab scientists found that inserting a small magnetic bead in the muscle tissue within the amputated residuum can perfectly measure how a muscle contract (via MIT)via MIT). It sends a message to the brain and the bionic prosthetic to contract in just milliseconds. Researchers call it magnetmicrometry (MM). They hope to replace electromyography for a better link to the peripheral nervous system to bionic limbs.

The procedure is also less invasive with a low regulatory hurdle, making it a cheaper alternative. People with low mobility due to accidents can also use the technology (via MIT). How? It provides a new way to send a signal from the injured muscle to the neurological system to a bionic exoskeleton. As a result, it can help the person walk with no problems. It can also work for rehabilitation after a nerve or spinal cord injury to stimulate muscle movement and bring better control of the body. This method provides an easier way to help patients have an everyday life with less hassle.
