Description
With the growing demand for sustainable and decentralized power sources to support the next generation of portable electronics and Internet of Things (IoT) devices, triboelectric nanogenerators (TENGs) have emerged as promising candidates for biomechanical energy harvesting1. In this study, we present the design and characterization of an origami-structured TENG fabricated using nylon and polysiloxane, selected for their complementary positions in the triboelectric series. The TENG was constructed using three layers of each material, each with dimensions of 5 × 5 cm, arranged to maximize contact area and mechanical deformation during operation.
Experimental evaluations were conducted under external mechanical stimulation using human hand tapping to mimic realistic biomechanical interactions. The device exhibited a maximum open-circuit voltage of 110 V and a short-circuit current of 11 μA, resulting in an output power of approximately 1.2 mW. These results underscore the potential of the proposed TENG for effective conversion of low-frequency biomechanical energy into electrical energy. The origami-inspired structure significantly contributes to the device's flexibility, resilience, and output performance, making it highly suitable for dynamic, high-traffic environments.
In conclusion, the origami-structured nylon/polysiloxane-based TENG represents a viable and efficient strategy for biomechanical energy harvesting, offering new avenues for powering low-energy devices within the broader scope of sustainable urban development and smart city applications.
