Matryoshka-inspired hierarchically structured triboelectric nanogenerators for wave energy harvesting

Ocean wave energy is an abundant resource of clean energy. However, having been explored for decades, there is still lacking efficient and economical technologies to convert water wave energy into electricity for large-scale applications Researchers have developed a new type of wave energy harvester, hierarchically structured triboelectric nanogenerator (HS-TENG), based on the triboelectric effect, targeting to harvest the huge blue energy for large-scale deployments.
