New Ultrasonic Sensor may Help Amputees Play Drums

A bionic hand with prosthetic arms evolved by way of US researchers has helped Jason Barnes, a musician who misplaced a part of his proper arm 5 years in the past, to play the piano and drums very easily.


Researchers from the Georgia Institute of Technology have created an ultrasonic sensor that mixes ultrasound alerts and system studying, permits amputees to keep watch over each and every in their prosthetic arms for my part.

‘New ultrasonic sensor that combines ultrasound signals and machine learning, allows amputees to control each of their prosthetic fingers individually.’

“Our prosthetic arm is powered by ultrasound signals. By using this new technology, the arm can detect which fingers an amputee wants to move, even if they don’t have fingers,” lead writer Gil Weinberg, Professor, on the varsity, mentioned in a observation.

Barnes, who misplaced his arm in 2012, used to be the use of prosthesis hooked up to his muscle groups and regulated by way of electromyogram (EMG) sensors for his day-to-day works. “Though they can detect a muscle movement, but the signal is too noisy to infer which finger the person wants to move,” Weinberg mentioned.

However, the brand new instrument attaches an ultrasound probe to the arm, which is able to assist medical doctors watch how muscle groups transfer.

When Barnes tries to transport his amputated ring finger, the muscle actions vary from the ones noticed when he tries to transport some other digit.

The crew fed each and every distinctive motion into an set of rules that may temporarily resolve which finger Barnes needs to transport.

The ultrasound alerts and system studying may locate steady and simultaneous actions of each and every finger, in addition to how a lot drive he intends to make use of, the researchers mentioned.

“It’s completely mind-blowing. This new arm allows me to do whatever grip I want, on the fly, without changing modes or pressing a button,” Barnes mentioned.

“If this type of arm can work on music, something as subtle and expressive as playing the piano, this technology can also be used for many other types of fine motor activities such as bathing, grooming and feeding,” Weinberg mentioned.

“I also envision able-bodied persons being able to remotely control robotic arms and hands by simply moving their fingers,” he famous.
