Here, we present a highly efficient untethered carbon-based non-contact hybrid nanogenerator that combines triboelectric and electromagnetic (EM) induction to convert biomechanical and ambient EM-waste energy into available electricity while enabling self-powered non-contact sensing. It uses graphite-like powder to capture and transport tribo-charges, and graphite-like textiles as tribo-charge reservoirs and stretchable conductors for EM induction. Notably, the use of recycled cotton fabric as a starting material underscores a sustainable and eco-friendly approach to material sourcing. The synergistic designs significantly enhance triboelectricity output (288 V, ± 1.23 μA, 4 Hz) and extend tribo-charge retention time beyond 10,000 min, achieving EM-induced electrification ( ± 15 V, ± 2.4 μA, 60 Hz). Even in non-contact condition, outputs remain 186.5 V (triboelectricity) and ± 9 V (EM waste) at a 1-mm distance, effectively enabling the powering of electronic devices. To the best of our knowledge, this is the first reported non-contact stretchable nanogenerator that can simultaneously harvest both energy types. Moreover, the performance and tribo-charge retention time are superior to those of reported carbon (graphene, graphene oxide, C<sub>60</sub>)-functionalized non-contact TENGs. Last, a multiplexing self-powered touchless gesture-sensing system is demonstrated.
