Cellulose-based materials have gained increasing attention for the development of low-cost, eco-friendly technologies, and more recently, as functional in triboelectric nanogenerators (TENGs). However, low output performance cellulose-based TENGs severely restricts their versatility employment emerging smart building city applications. Here, we report a high commercial cellulosic material-based energy harvesting floor (CEHF). Benefiting from significant difference properties between weighing nitrocellulose papers, surface roughness achieved by newly developed mechanical exfoliation method, large overall contact area via multilayered device structure, CEHF (25 cm × 15 1.2 cm) exhibits excellent with maximum voltage, current, power peak values 360 V, 250 μA, 5 mW, respectively. It can be directly installed or integrated regular flooring products to effectively convert human body movements into electricity shows good durability stability. Moreover, wireless transmission sensing system that produce 1:1 footstep-to-signal (transmitted received) ratio is instantaneously powered TENG based entirely on first time. This work provides feasible effective way utilize construct self-powered systems real-time
