A paper by Dr Bryce Dorin has been published in Applied Physics A, where our recently developed direct-laser-writing technique was put to use contacting randomly distributed and encapsulated components.
In this work, Bryce distributed and encapsulated commercial microLEDs in a polyimide/epoxy system, and used direct laser writing to convert the insulating polyimide to conducting graphitic material. He demonstrated high quality connections, allowing for arbitrary quasi-3D wiring within an insulating package.
