Fine-tuned brain-computer interface makes prosthetic limbs feel more real

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.

For years now, brain-computer interfaces (BCI) have incrementally advanced, giving people with spinal injuries or lost limbs the ability to control prosthetics and computer cursors using their signals. But even though the tech has made strides, the replicating subtle, delicate, nuanced sensations of touch has remained just out of reach. Now, however, a team of researchers from the Cortical Bionics Research Group believe they have made a major br…

Brain-connected implants help paralyzed patients feel objects and shapes

In two recent studies led by UChicago scientists, users of a bionic hand were able to “feel” sensation in such detail that they could blindly identify a letter of the alphabet by tracing it with a fingertip, and users of a bionic arm could control a steering wheel. The studies represent a significant breakthrough in the development of neuroprosthetics. “I distinctly remember one of the participants, the first time he felt something, started cryi…

Brain-Computer Interfaces (BCIs) are revolutionizing gaming and entertainment, enabling users to control devices with their minds. Despite challenges such as difficulty in use and fatigue, the BCI market is expected to grow from $1.4 billion in 2020 to $5.5 billion by 2025. Advances in neurotechnology, including functional near-infrared spectroscopy (fNIRS) and electrocorticography (ECoG), are driving growth in the industry. However, ethical con…

Researchers convey tactile touch in bionic hand via brain implants

Recent advances in the field of neuroprosthetics have brought us closer than ever to restoring the sense of touch for individuals who have lost limb functionality. A research team led by neuroscientist Charles Greenspon at the University of Chicago has made significant strides in developing brain-computer interfaces (BCIs) that not only facilitate movement in robotic prosthetic hands but also replicate the complex sensations of touch. This cutti…
