'Bio-paper' implant: Personalized wireless electrotherapy for Parkinson's

An innovative biodegradable paper that sticks to the brain’s surface like a Band-Aid and delivers electrical stimulation wirelessly could revolutionize the treatment of neurological diseases like Parkinson’s and Alzheimer’s, according to a new study.

Researchers from the Uhlan National Institute of Science and Technology (UNIST), South Korea, have developed a biodegradable, wirelessly activated ‘bio-paper’ implant that avoids these issues. “The combination of nanoscale magnetoelectric and biodegradable fibrous materials offers advantages over traditional system-level wireless electronic devices that rely on intricate assembly of bulky components that cannot be redesigned post-fabrication,” said the researchers. Its physical properties mean the ‘paper’ will conform to curved, complex surfaces – like the brain’s – and can be cut, rolled, and folded while retaining functionality.
