Star Wars-Motivated Bionic Hand Allows Amputees To Direct All Prosthetic Fingers

An ultrasonic sensor is developed by scientist that enables the amputees to manage every prosthetic finger independently, making the path for a Star Wars-like bionic hand. Fine motor hand signals are provided by the sensor that are not achievable with the existing devices.

Jason Barnes is the first amputee to employ this technology. He is a musician who, 5 Years ago, lost piece of his right arm. Now, Barnes is capable of playing drums and piano for the first ever time after his accident. The tool is motivated by the bionic hand provided to Luke Skywalker in the series “Star Wars,” as stated by the researchers.

Gil Weinberg, Georgia Tech College, the US, said, “Our prosthetic arm is motorized by ultrasound signals. With the use of this novel tool, the arm can sense which finger an amputee wish to move, even though they do not have fingers.”

No longer Barnes has his hand and the majority of his forearm; however, does have the muscles in his remaining limb that direct his fingers. Previously, he was using prosthesis connected to his muscles and directed by EMG (electromyogram) sensors.

Weinberg said, “EMG sensors are not exceptionally precise. They can sense movement of a muscle, but the gesture is too boisterous to deduce which finger the individual wishes to move. We attempted to enhance the pattern recognition from EMG for him but couldn’t achieve finger-by-finger control.” Now, the research team has connected to the arm an ultrasound probe. The identical type of probe physicians uses to observe babies within the womb can observe how muscles of Barnes moved.

Weinberg said, “If this sort of arm can function on music, this technology can also be utilized for several other sorts of fine motor activities such as grooming, feeding, and bathing. Also, I visualize able-bodied individuals being capable of distantly manage robotic hands and arms by merely moving their fingers.”
