A tiny, flexible machine might one day help neuroscientists eavesdrop on electrical activity in the brain, allowing them to pinpoint and potentially treat seizures.
Inserted into the skull through a hole just 1 to 2 centimeters wide, the flower-shaped device unfurls a flexible array of sensors that contact the brain’s surface, allowing it to monitor electrical activity, researchers report May 10 in Science Robotics. A successful demonstration on a minipig suggests the device could be a less invasive way to place sensors directly on the brain, which currently can require removal of a large section of skull.
