In this work, authors used waste plastic bottle and aluminIum foil further modified with graphene oxide as triboelectric material to construct a triboelectric nanogenerator (TENG). The proposed device is based on a single electrode system. The operating mechanism involves the generation of energy by tapping the surfaces with hand or finger. TENG material provided good response and charge retaining capacity. The device is eco-friendly; provide easiness, and simplicity of process. The substrate material is of inertness nature so can be used in wet conditions as well. The results were conducted by measuring the open-circuit voltage, short circuit current, total charge density, and power density at different frequencies from 1Hz to 3Hz. The TENG generated approximate open-circuit voltage, short-circuit current, charge density, and maximum power density values of 1400 V, 45 µA, 120 nC/m², and 300 μW/cm², respectively by finger pressing and releasing. The application was run to charge 2 nF and 10 nF capacitor by TENG and successful results were obtained. This study provides an effective method for developing a cost-effective TENG without the use of complex surface micro-/nano-texturing.
