A wave energy generating device based on friction nanotechnology

At present, the field of marine transportation facilities is developing rapidly, but it has significant deficiencies in energy supply. As a recent research focus, the friction nanogenerator offers several advantages, including a simple structure, low cost, high power density, flexible material selection, and higher conversion efficiency (23%-50%) for low-frequency vibration energy such as wave energy. Its unique thin film friction power generation structure is more conducive to miniaturization, high-density superposition, and array configuration of power generation devices. However, the design of the device’s structure and the selection of film materials have a crucial impact on power generation efficiency.Considering the existing issues with wave energy generation devices and the urgent need for new energy development, this study proposes a wave energy utilization device based on back grid electrode type multi-layer and multidirectional friction nano power generation. The aim is to achieve efficient absorption of wave energy while maintaining high power generation efficiency through a simple structure and at low cost.
