Discovering a Sustainable Energy Source: The Fungal Biobattery
Imagine a battery that functions by consuming nutrients rather than relying on conventional charging methods. Researchers at Empa have successfully developed a groundbreaking 3D-printed fungal battery that is both biodegradable and alive. This innovative energy source holds the potential to power sensors utilized in agricultural or remote environmental research settings. Ultimately, once the energy needs are met, this unique battery disintegrates naturally. The findings are featured in *ACS Sustainable Chemistry & Engineering*.
The Power of Fungi: A Versatile Organism
Fungi possess diverse characteristics and are more closely related to animals than plants, encompassing an array from edible varieties to large superorganisms found in nature. They exhibit numerous functionalities ranging from producing medicines to causing diseases. Recently, scientists at Empa have uncovered yet another trait: their capacity to generate electrical energy.
A dedicated three-year research initiative undertaken by researchers from Empa’s Cellulose and Wood Materials laboratory has led to the creation of an operational fungal-powered cell, also known as a microbial fuel cell (MFC). While these cells do not generate significant electric power like traditional batteries, they can effectively support small devices such as temperature sensors for several days—critical in both agricultural practices and ecological investigations. One major advantage is that these fungal batteries are entirely non-toxic and decompose naturally after usage.
An Innovative Approach with Microbial Fuel Cells
Traditionally powered by bacteria, microbial fuel cells harness living organisms’ metabolic processes for electricity generation; however, this project marks the first instance where fungi have been employed as central components within such cells.
“We’ve combined two distinct types of fungi into one functional unit,” explains Carolina Reyes from Empa’s research team. “Each species complements the other’s metabolic functions.” On one side (the anode), they use yeast which releases electrons during metabolism; meanwhile, white rot fungus inhabits the cathode section where it produces enzymes aiding electron capture—facilitating their extraction from the cell.
A Fusion of Biology and Technology
The design incorporates these fungi right within its structure rather than planting them later on; through advanced 3D printing technology crucial components for optimal nutrient access are created meticulously while integrating fungal cells into printing materials themselves.
“Finding suitable materials conducive for fungal growth was complex enough,” notes Gustav Nyström who leads this laboratory division. “Additionally, our ink must be easily extrudable without damaging delicate cells while being both electrically conductive and capable of biodegrading.” Utilizing extensive expertise in soft bio-based material 3D printing helped develop cellulose-based inks—suitable as nutrients for fungi post-operation allowing seamless battery disposal post-use.”
Challenges Faced Along This Scientific Journey
This living-material integration inherently posed several challenges across various disciplines including microbiology alongside engineering principles establishing interoperability between functionality analysis frameworks traditionally used within electrochemistry against those concerned primarily with biology-based substrates like 3D printed inks produced here!
The next stage involves enhancing durability further while exploring alternative funguses suitably adaptable towards sustainable electric production capabilities filling gaps currently unmet! According conversations held among study leaders emphasize ongoing untapped potentials existing outside mainstream explorations proves advantageous expanding horizons concerning usable materials drawn forth through advances realized contrasting earlier generations’ approaches!
