And by matching the human body, we were able to see improved benefits,” Gregory Clark, associate professor of the University of Utah biomedical engineering, says.
Enhanced sensory feedback
As the technology evolved, researchers began focusing on integrating sensory feedback into prosthetics. The sensory feedback system operates through a combination of sensors embedded in the prosthetic and advanced algorithms that interpret the data. These sensors relay information to the user’s nervous system, often through electrodes placed on the skin or implanted in the body. This direct connection allows for a more seamless integration between the prosthetic and the user’s own sensory perception, resulting in a more intuitive experience.
For many users, the ability to feel through their prosthetic arm represents a profound transformation in their daily lives. Enhanced sensory feedback not only improves functionality but also boosts confidence and independence. Users can navigate complex tasks—like pouring a cup of coffee or shaking hands—without the fear of dropping or mishandling objects, leading to a more enriching and fulfilling life.

Cutting-edge artificial intelligence
Just providing sensation is a big deal, but the way you send that information is also critically important, and if you make it more biologically realistic, the brain will understand it better and the performance of this sensation will also be better.
Gregory Clark, associate professor of the University of Utah biomedical engineering
At the heart of the Luke Arm’s functionality is its AI-powered control system. The arm learns from the user’s movements and preferences, adapting its responses over time. This means that the more a user interacts with the arm, the better it becomes at anticipating their needs, ultimately leading to a more seamless and intuitive experience. With machine learning capabilities, the Luke Arm can customise its settings based on individual habits. For instance, if a user frequently adjusts their grip for specific tasks, the AI can recognise this pattern and make automatic adjustments, making daily activities easier and more efficient. “Just providing sensation is a big deal, but the way you send that information is also critically important, and if you make it more biologically realistic, the brain will understand it better and the performance of this sensation will also be better,” says Clark.
