DARPA looking to build ‘transient electronics’ devices

From KurzweilAI.net:

The sophisticated electronics used by warfighters in everything from radios, remote sensors and even phones can now be made at such a low cost that they are pervasive throughout the battlefield. But it is almost impossible to track and recover every device. 

These electronics are often found scattered across the battlefield and might be captured by the enemy and repurposed or studied to compromise DoD’s strategic technological advantage. 

What if these electronics simply disappeared when no longer needed? 

DARPA has announced the Vanishing Programmable Resources (VAPR) program, with the aim of revolutionizing the state of the art in transient electronics — electronics capable of dissolving into the environment around them.
