The same systems are potentially suitable for directly tagging food, monitoring its quality, and developing edible soft actuators control and sensing abilities. Designing appropriate edible power sources is critical to turn such a vision into real opportunities. We propose electrically conductive edible composites based on ethylcellulose and activated carbon as enabling materials for energy harvesting and storage. Free-standing, phase-separated bi-layered films, insulating at the top and with low electrical resistivity (~10 Ω cm) at the bottom, were produced with a scalable single-step process. Food additives can tune the mechanical and triboelectrical properties of the proposed edible films. We demonstrated their successful operation as electropositive elements in organic triboelectric nanogenerators (TENGs) and as elec trodes in fully edible supercapacitors (SC). The TENGs showed ~60 V peak voltage (root mean square power density ~2.5 μW cm− 2 at 5 Hz), while the SC achieved an energy density of 3.36 mW h g− 1 , capacity of ~ 9 mAh g− 1, and stability for more than 1000 charge-discharge cycles. These results show that the combination of ethyl cellulose and activated carbon, and the control over their mixture, allow on-demand edible devices for energy generation and storage, serving future edible and green electronics scenarios. | URI: | https://open.uns.ac.rs/handle/123456789/32632 | ISSN: | 2211-2855 | DOI: | https://doi.org/10.1016/j.nanoen.2023.108168 | Prаvа: | Attribution-NonCommercial-NoDerivs 3.0 United States |
