| Abstract | With the growing demand for integrated smart home systems driven by advancements in the Internet of Things (IoT) and smart city initiatives, the need for efficient, simple, and self-sustaining sensors has become essential. Triboelectric nanogenerators (TENGs) have recently emerged as a promising device for both energy harvesting and sensing. However, the fabrication of different TENG layers using conventional techniques is often complex, time-intensive, and involves multiple processing steps. Here, a single-step multi-material 3D printing (MMP) approach is used to fabricate the fully functional TENG device, consisting of positive and negative triboelectric layers, current collectors and supporting substrate. Nylon 6 and carbon/polyvinylidene fluoride (C/PVDF) filaments are selected for positive and negative triboelectric layers, respectively and conductive carbon/polylactic acid (C/PLA) filament was selected for both current collectors and wood/PLA is selected for both top and bottom supporting layers. The MMP-TENG is integrated with electronics to showcase its capability for remote monitoring in smart home settings to detect real-time fall detection and security monitoring. This research will pave the way for fabricating a smart floor for security monitoring and energy generation in a smart building. © 2025 The Author(s).
