This soft robotic skull implant could change epilepsy treatment

After being approached by a neurosurgeon seeking a less invasive method to treat conditions that require a brain implant, a team of researchers at Switzerland’s Ecole Polytechnique Fédérale de Lausanne led by neurotechnology expert Stephanie Lacour started working. They took inspiration from soft robots to create a large cortical electrode array that can squeeze through a tiny hole in the skull. They published their findings in Science on May 10. While microelectrode arrays were first invented decades ago, the use of these arrays for deep brain stimulation in epilepsy patients has only became FDA approved in the past handful of years. Even so, current devices often have certain trade offs, be it electrode resolution, cortical surface coverage, or even aesthetics, the authors write in their paper.
