Next time you go for a brain scan; you could actually see dissolvable electrodes.
Hmmm
Scientists at the University of Pennsylvania in a study funded by the Defense Advance Research Projects Agency (DARPA) 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,” Brian Litt, senior co-author on the study and a professor of neurology, neurosurgery and bioengineering at UPenn, said in a statement.
The dissolvable electrodes also “eliminate the risks, cost, and discomfort associated with surgery to extract current devices used for post-operative monitoring,” Litt said. Scientists recently published their findings online in Nature Materials.
