The Defense Advanced Research Projects Agency (DARPA) researchers are building a system of dissolvable, biocompatible electronics that could be put to use in implantable medical treatments.
Made of ultrathin sheets of silicon and magnesium encapsulated in silk, the components combine to become a water-soluble material that will dissolve in a matter of days, hours, or minutes.
By tweaking the thickness and crystallinity of the silk, scientists can determine how long the electronics will take to dissolve.
The technology can be used to create an implantable device that would serve as a non-antibiotic, programmable bactericide, according to DARPA. It would dissolve harmlessly into the body, where low levels of silicon and magnesium are naturally occurring. The biocompatible components can prevent surgical site infection and offer remote patient care without extraction surgery – perfect for overseas soldiers.
