DARPA researchers have created electronic systems and components using ultrathin sheets of silicon and magnesium encapsulated in silk, a biocompatible material. The thickness and crystallinity of the silk determines how long the electronics take to dissolve: days, hours, or even minutes. Silicon and magnesium are naturally occurring at low levels in the human body, and since the amount of material used in these devices is below physiological levels these electronics are biocompatible and eco-friendly.
