The development of green, low-cost and disposable micro power sources that can be self-sustainable are highly needed in the field of biobatteries, ingestible medical devices, wearable sensors, and smart textiles. Moreover, the improvement of small-scale devices that can be globally used to temporarily collect real-time information from the environment are highly required. To achieve a fully biodegradable battery we will develop water-based inks composed of cellulose and cellulose derivatives. For this purpose, two generations of biobatteries using fungi as oxidation catalyst will be manufactured; (i) The first generation will target short single use operation and will stop working when the provided source of nutrients is depleted by the fungus. (ii) The second generation will have an extended lifetime owing to the combination of fungi and microalgae working in symbiosis - the microalgae will provide the carbon source for the fungus and the fungus will provide the mineral nutrients for the microalgae - to ensure extended operation for continuous sensing functionality. This generation of biobattery will continuously operate until it is decomposed into its surroundings. The biobattery will be made of a continuous nanocellulose sheet that the user will assemble in a simple two-step folding process, and activated by providing a small volume (~1 mL) of water to the dormant microorganisms. The objective is that the results of this project leads to an Empa spin-off company that aims to bring the developed fungal biobatteries to the market.
Was ist das Besondere an diesem Projekt?
This project aims at solving the key challenge to develop a reliable technology that can autonomously and efficiently provide stable electrical supply even in resource-limited environments. Additionally, a successful development of green, low-cost and disposable power source that can be self-sustainable may assist in moving the research and technological developments within the fields of environmental sensing, ingestible medical devices, wearable sensors, and smart textiles forward.
The project will begin in April 2020.
