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 is a major limitation of current upper body prostheses?

• They are too heavy to wear.

• They require frequent maintenance.

• They are too expensive for most users.

• They lack fine motor control for daily tasks.

How do engineers at George Mason University improve prosthetic control?

• By implementing voice control.

• By imaging muscle deformation with ultrasound.

• By using stronger motors.

• By reducing the weight of the prosthetic.

What technology is used to sense muscle activity in the new method?

• Infrared sensors

• Ultrasound technology

• Magnetic resonance imaging

• Electroencephalography

What is the anticipated timeline for commercial availability of the new prosthetic system?

• Over 10 years

• 5 to 10 years

• 3 to 4 years

• 1 to 2 years

What is the team at George Mason University currently working on regarding the ultrasound system?

• Integrating it with virtual reality

• Miniaturizing the system to fit under the prosthetic shell

• Increasing the speed of the motors

• Developing a wireless version
