Magnetic Sensors Track Muscle Length

Using a simple set of magnets, researchers have devised a sophisticated way to monitor muscle movements, which they hope will make it easier for people with amputations to control their prosthetic limbs. The researchers have demonstrated the accuracy and safety of their magnet-based system, which can track the length of muscles during movement. The studies, performed in animals, offer hope that this strategy could be used to help people with prosthetic devices control them in a way that more closely mimics natural limb movement.
