Heat-Triggered, Self-Destructing Electronic Devices
Added May 28, 2015 | Rate View top rated
University of Illinois researchers have developed self-destructing electronic devices, a step toward advanced biomedical implants as well as reduced electronic waste and boosted sustainability in device manufacturing. The heat-triggered devices use magnesium circuits printed on very thin, flexible materials. The researchers trap microscopic droplets of a weak acid in wax, and coat the devices with the wax. When the devices are heated, the wax melts, releasing the acid. The acid dissolves the device quickly and completely. To remotely trigger the reaction, researchers embedded a radio-frequency receiver and an inductive heating coil in the device. The user can send a signal to cause the coil to heat up, which melts the wax and dissolves the device.

Very interesting. I see one huge problem with this technology, governments including ours can get the appropriate radio wave and take out the individuals ability to continue the use of their equipment without a major device like EMP. While I applaud the effort to sustainability, which is great, the downside of this is also bad.
