This DARPA video shows how a new class of electronics can safely dissolve into small amounts of liquid. Transient electronics are electronic systems and components that use ultrathin sheets of silicon and magnesium encapsulated in silk. The thickness and crystallinity of the silk determines how long the electronics take to dissolve. Do you remember the SciFi movies that they destroy all evidence by dropping everything into the water? It is not fictional now! It is a reality!
