Researchers harness ultrasound technology to give amputees a better grip with their prosthetics.

The video discusses the limitations of current upper body prostheses, which are controlled by electrodes detecting muscle activity. Engineers at George Mason University, funded by the National Science Foundation, have developed a new method using ultrasound technology to image muscle deformation, allowing for better control of prosthetics. This method can differentiate between 15 distinct hand and wrist movements, improving the user's ability to perform tasks. The team is working on miniaturizing the system for commercial use, aiming to provide users with enhanced functionality.

What are the anticipated advancements in prosthetic devices over the next 5 to 10 years according to the text?

In what ways do test subjects report improvements in their ability to use prosthetics with the new ultrasound system?
