Researchers in Austria have discovered a mushroom that can form the basis of electronic circuit boards or separators in batteries. This could make it much easier to recycle electronics.
The “skin” is based on a fungus growing naturally on dead hardwood in mild temperate climates. They possess high thermal stability and flexible shape, allowing the soldering of electronic components and facilitating the fabrication of electronic sensor boards. Plus, they can withstand over 2,000 bending cycles.

Mushrooms can do some amazing things. I watched a TED talk in which they used them for everything from reclaiming land to purifying water. There are houses you can grow as mushroom panels in a couple of days now, I read. Useful allies.
