Electronics Vanishing in the Environment: DARPA

 

What are VANISHING PROGRAMMABLE RESOURCES (VAPR)?  From the DARPA website

What if these electronics simply disappeared when no longer needed? DARPA announces the Vanishing Programmable Resources (VAPR) program with the aim of revolutionizing the state of the art in transient electronics or electronics capable of dissolving into the environment around them. Transient electronics developed under VAPR should maintain the current functionality and ruggedness of conventional electronics, but, when triggered, be able to degrade partially or completely into their surroundings. Once triggered to dissolve, these electronics would be useless to any enemy who might come across them.

The Vanishing Programmable Resources (VAPR) program seeks electronic systems capable of physically disappearing in a controlled, triggerable manner. These transient electronics should have performance comparable to commercial-off-the-shelf electronics, but with limited device persistence that can be programmed, adjusted in real-time, triggered, and/or be sensitive to the deployment environment.  VAPR seeks to enable transient electronics as a deployable technology. To achieve this goal, researchers are pursuing new concepts and capabilities to enable the materials, components, integration, and manufacturing that will realize this new class of electronics.

Transient electronics may enable a number of revolutionary military capabilities including sensors for conventional indoor/outdoor environments, environmental monitoring over large areas, and simplified diagnosis, treatment, and health monitoring in the field. Large-area distributed networks of sensors that can decompose in the natural environment (ecoresorbable) may provide critical data for a specified duration, but no longer. Alternatively, devices that resorb into the body (bioresorbable) may aid in continuous health monitoring and treatment in the field.

Companies involved IBM: IBM plans is to utilize the property of strained glass substrates to shatter as the driving force to reduce attached CMOS chips into Si and SiO2 powder.
