US EditionNeurotechnology study delivers ‘another level’ of touch to bionic hands
- Researchers have made significant advancements in neurotechnology to recreate tactile feedback for bionic hands, as documented in papers published in Nature Biomedical Engineering and Science.
- The project was led by Giacomo Valle, PhD, who is now at Chalmers University of Technology in Sweden, following the passing of Sliman Bensmaia, PhD, in 2023.
- The studies show that a brain-computer interface allows users to control bionic limbs and experience complex touch sensations, enhancing independence for those with limb loss or paralysis.
- Giacomo Valle stated, 'We are in another level of artificial touch now,' highlighting the potential for more vivid sensory feedback with bionic hands.

Brain stimulation enables nuanced feeling in prosthetic hands
You can probably complete an amazing number of tasks with your hands without looking at them. But if you put on gloves that muffle your sense of touch, many of those simple tasks become frustrating. Take away proprioception - your ability to sense your body's relative position and movement - and you might even end up breaking an object or injuring yourself.
An innovative study published in the journal ' Science ' presents a revolutionary advance in the design of extracorporeal bionic limbs capable of imitating the sense of touch. Until now, bionic prostheses allowed people with spinal cord injuries to perform daily tasks, such as picking up objects, but failing to replicate the touch sensation.This new development uses brain stimulation to generate a complex tactile perception while employing a bio…
Artificial touch: Brain-controlled bionic hand now senses edges and motion
A complex sense of touch for individuals living with spinal cord injuries is a step closer to reality. A study published in Science, paves the way for complex touch sensations through brain stimulation while using an extracorporeal bionic limb, that is attached to a chair or wheelchair. The paper is titled "Tactile edges and motion via patterned microstimulation of the human somatosensory cortex."
