Functional electronic devices that can dissolve in water or other fluids at a set point in time offer up a myriad of possibilities to the world.

DARPA, the Defense Advanced Research Projects Agency, has funded a successful study conducted by researchers at Northwestern University, Tufts University and the University of Illinois at Urbana-Champaign that showcased the feasibility of dissolvable or transient electronics to the world. How we can use this technology in the real world is where things get interesting.
