| Abstract Scope |
Driven by the rapid growth of Internet of Things (IoT) and its role in building smart buildings and cities, sub-floor sensors based on triboelectric nanogenerators (TENGs) that are primarily composed of cellulosic materials have gained increasing attention due to the low-cost, sustainability, and abundance of such materials. In this work, we developed a high output performance of a commercial cellulosic material-based energy harvesting floor (CEHF). Benefiting from the significant difference in the triboelectric properties between weighing and nitrocellulose papers, high surface roughness achieved by a newly developed mechanical exfoliation method, and large overall contact area via a multilayered device structure, a wireless transmission sensing system is instantaneously powered by a TENG based entirely on cellulosic materials for the first time. This work provides a feasible and effective way to utilize eco-friendly cellulosic materials in constructing self-powered wireless transmission systems for future smart cities. |
