Scientists Develop Plastic Beads That Generate Electricity Through Friction

The innovative triboelectric technology offers a sustainable, cost-effective way to harvest energy without relying on traditional power sources.

Researchers from multiple institutions have developed triboelectric nanogenerators (TENGs) using tightly packed plastic beads to generate electricity through friction.
The triboelectric effect occurs when physical contact between dielectric materials creates electric charges, similar to static electricity from rubbing a balloon on hair.
Melamine-formaldehyde beads showed the highest efficiency, as their low elasticity enhances charge retention and transfer.
This technology could lead to self-powered devices, wearable smart clothing, and other sustainable energy applications that do not require batteries or charging.
Further research is needed to improve efficiency and reliability before the technology can be widely implemented in real-world products.
