Getting the grip!
Researchers harness ultrasound technology to give amputees a better grip with their prosthetics. National Science Foundation-funded engineers at George Mason University have found a way to help people get a better grip with their prosthetics.-- By imaging muscle deformation from the remaining muscles in the arm the team is able to understand the subjects intended movements. The team uses powerful ultrasound technology to send sound waves deep into the body to sense this muscle activity. Their computer algorithms use these signals to learn to accurately differentiate between 15 distinct hand and wrist movements.
