Finnish design studio Aivan has created Korvaa headphones, in the production of which yeast and mushrooms were used.
This writes Dezeen.
In total, the construction uses six “components” grown from microbes.
Headphone earband is made of bioplastic, created from lactic acid, obtained from baking yeast.
The lining, in which the speakers are embedded, is made using the Trichoderma reesei mushroom - in industry they are used to produce pulp. From the fungus, a protein called hydrophobin is obtained, which is known to form a dense water-repellent foam. Aivan mixes cellulose with hydrophobin to obtain a stable, yet soft structure.
As a mat rial, which for additional convenience are covered with lining, a part of the mushroom called mycelium is used. It feels like skin to the touch.
Headphone speakers also cover the “case”, which is made from web-based protein, one of the most durable materials in the world. It is noted that this protein can also be used for the production of body armor.
The creators note that in its current form, the Korvaa is only a concept that cannot replace a familiar pair of headphones. His goal is to show the potential of technology called synthetic biology.
