The Empire Strikes Back – Luke Skywalker Prosthetic Hands

To lose a hand is to lose a part of yourself, Gregory Clark, associate professor of biomedical engineering on the University of Utah mentioned. Moreover, while prosthetic hands have been in use for thousands of years, there is room for growth.

Researchers on the University of Utah, with the help of different organizations together with Blackrock Microsystems and DEKA, have been on a mission to do that. They’ve developed a prosthetic system that may allow patients to regain their sense of touch.

“Traditional prosthetic hands lack sensory suggestions, which makes them clumsy to control and makes them feel unnatural,” mentioned Clark.

As a result, the staff added sensory feedback to an advanced bionic arm called the LUKE arm. It is named for the robotic arm Luke Skywalker receives in “The Empire Strikes Back.”

They used the output from arm sensors to control the stimulation of sensory nerve fibers which convey info to the mind and create the sensation of touch. To recreate that sensation, electrodes had been connected to the inside of the nerves.

The sensations embody different types of touch, such as pressure, flutter or vibration, temperature, and ache. Based on Clark, customers can also feel the location and contraction of their muscles, though the muscles aren’t there.

Moreover, simply because the brain can interpret the electrical signals, the motor signals from the brain register with the LUKE as effectively.

Clark stated that when a person thinks about shifting their hand, whether they have one or not, the brain will ship a motor signal down the nerves.

Keven Walgamott was one of the participants in the study. He used the arm for the first time in 2017.

The prosthetic is pending FDA approval, Clark mentioned. However, they are hoping to begin take-house trials inside the coming months. They’re also hoping to make wireless versions so users don’t must have wires sticking out as they do with the current model.

Commercial versions will take years to become available.
