The concept car, called the BMW iX Flow, uses electronic ink technology normally found in e-readers to transform the car's exterior into a variety of patterns in gray and white.

It has been behind several technological innovations, including the electronic ink used in the Amazon Kindle, and video game Guitar Hero.

According to the abstract, the mushroom was constructed like this: first, the researchers 3-D printed an electronic ink containing graphene nanoribbons onto the cap of a living mushroom.

Then, they printed a bio-ink containing cyanobacteria onto the cap, which intersected with the electronic ink.

They had previously used an electronic ink to embed graphene nano-ribbons on to the surface of the fungus to collect the current.
