Things we do with electronics nowadays are amazing. Processors in computers contain billions of transistors, each measuring a few millionth of mm in size. Airbags sensors in cars save lives every day, measuring the sudden deceleration of vehicles and ordering the deployment of pillows at great speed.

Techniques we use to construct these components show an important limitation, however -- all fabrication processes are inherently two-dimensional. Micro-technology is tied to photo-lithography which consists on applying a mask on a planar surface, silicon wafers and such, through UV illumination. Ma...
