Coco on Instagram: "Triboelectric nanogenerators (TENGs) generate power through friction, while Polyvinylidene Fluoride (PVDF) generates electricity when bent or stretched. By combining these technologies, I’m developing a prototype for a rechargeable cond0m. I know many of you have access to powerful chargers at home, but not everyone is so fortunate. My goal is to create something that can help those who need it most."
