Imagine brain implants that completely dissolve and fade away after a period of time.
That’s just what a team of researchers at the University of Pennsylvania have developed. They’ve created sensors, made of layers of molybdenum and silicon, that can monitor brain signals (and even deliver signals), and then melt away without a trace.
The research was published online in the journal Nature Materials, and represents a great forward leap in biosensing technology. According to lead researcher Brian Litt, MD, it bypasses “the risks, cost, and discomfort associated with surgery to extract current devices used for post-operative monitoring.”
The devices will be especially useful for mapping the neurophysiology and neural patterns of certain mental and neurological disorders—for instance, Parkinson’s disease, depression, and epilepsy. Further useful applications will include post-operative monitoring, and the placement of devices involved in heart and brain surgery.
