As we see the great impact of technology on our life in today's era.
Leipzig, Germany: The bottom layer of the battery and the electronic chip is made of plastic and cannot escape into the environment. Now, new research suggests that the top layer of the sponge can be replaced, making it easier to make electronics and eco-friendly devices greener. It is a type of fungus that has a thin layer of skin on it.
This has the advantage that it also facilitates the recycling of obsolete electronic devices. We know that the entire system of metal electronic devices, large and small, are placed on an insulating or cooling layer called a "substrate." All electronic chips are made from non-recyclable plastic polymers. Currently, 50 million tons of e-waste is generated every year.
Scientists at the Johannes Kepler University in Linz, Germany, conducted a study of fungi. In his opinion, most electronic devices cannot be recycled and are of very low value. Ganoderma mushrooms grow on rotting wood and are protected from bacteria and other pathogens by a mycelium shell.
Experts took it out, dried it, and heated it to 200 degrees Celsius until it was paper-thin and ready for use as a circuit board. Mushroom skins can last for years and remain part of the chip for decades if protected from UV rays and moisture. Dissolves in days. In the next step, the researchers created an electrical circuit in the mushroom skin. This started to work well and proved to be a good replacement for plastic substrates. After that, it did not break even after being bent 2000 times.
Experts assume that the battery and Bluetooth components can condense. Sponges are also ideal for short-term electronic devices such as radio tags and part-time sensors. Kaltenbrunner and his colleagues attempted to use the skin of the fungus Ganoderma lucidum as a biodegradable electronic substrate. Fungi that normally grow on rotten wood form a skin that protects the mycelium, the root-like part of the fungus, from foreign bacteria and other fungi. Researchers did not grow skin with other fungi tested.
When they removed the skin and dried it, they found it flexible, an excellent insulator capable of withstanding temperatures in excess of 200°C (390°F), and about the thickness of a sheet of paper. It's like a circuit board.
