Abstract: Recycling of plastic and waste materials to fabricate smart devices can reduce their environmental damage. These materials can be used to develop triboelectric nanogenerators (TENGs) that harness renewable energy and transform it into electrical energy. This energy can power future Internet of Things (IoT) devices and generate self-powered sensors. The TENGs can reuse natural and plastic waste to fabricate their triboelectric layers and support structures. Herein, we report a novel eco-friendly TENG based on recycled and natural waste materials composed of ethylene vinyl acetate (EVA) foam and banana leaf. This nanogenerator can convert the vibrations into electrical energy for smart home security systems, using a simple electromechanical structure, an easy operating principle, and a microcontroller with connection to IoT. This TENG can reach a peak–to–peak open circuit voltage of 604 V, and a power density of 12.65 mWm−2 with a load resistance of 30 MΩ at 30 Hz. This nanogenerator has a stable performance with ability to power small electronic devices and IoT sensors. In addition, this TENG can contribute to the circular economy using recycled and waste materials to harvest green energy from different vibration sources.
