Science is Fun Fridays!
1st Place for the 2024 BCI Award has gone to an international team who have encoded complex touch sensations into a bionic hand. "We conveyed tactile sensations related to orientation, curvature, motion, and 3D shapes for a participant using a brain-controlled bionic limb," explains lead author, Professor Giacomo Valle. In patients with paralysis caused by spinal cord injury, the electrical signals that would normally carry tactile information from the hand to the brain are blocked. With the brain-computer interface, patients are able to experience the feel of objects. We tend to focus more on our senses of sight and hearing, but touch also provides abundant data about the world around us. Not to mention the importance of human touch - another study has developed temperature sensing prosthetic limbs. But in this case, the limb is extracorporeal, attached to a wheelchair.
