Scientists at the University of Pennsylvania are developing implantable electrodes for brain monitoring that melt away at a predetermined rate. The devices could come in handy for monitoring and treating certain neurophysiological disorders such as Parkinson's, depression and chronic pain.
The electrodes, which are made from layers of silicon and a chemical element, molybdenum, dissolve at a known rate according to thickness. The devices can provide "continuous streams of data for guiding medical care over predetermined periods of time. The dissolvable electrodes also eliminate the risks, cost, and discomfort associated with surgery to extract current devices used for post-operative monitoring.
