Eco-friendly electronics of the future will be designed to disappear

Researchers at Scandinavian research organization SINTEF have made progress in developing components that dissolve in water. Printed on a silicon wafer, the components contain extremely thin circuits — only a few nanometers thick — that are designed to transfer energy. They are made of a combination of magnesium, silicon, or silicon with a magnesium additive; are water-soluble; and disappear after a few hou ...

This is actually the first published part of an afterschool learning project I'm working on that demonstrates the Arduino UNO beyond flashin ...
