Bionic Mushroom Generates Power

Nov-07-18 A bionic mushroom capped by a 3D-printed structure could offer a new source of bio-electricity.

The power-generating mushroom system was created by a team from the Stevens Institute of Technology by using an electronic ink containing graphene nanoribbons to print a branching pattern on the cap of a living mushroom. A second spiral pattern using cyanobacteria bio-ink was then printed on the cap, with the new pattern intersecting the electronic ink. When a light was shone on the mushroom, the bacteria began to photosynthesize, ultimately generating a current of about 65 nanoAmps. The team is now investigating ways to arrange the mushrooms in an array to generate even more power.
