Waste polystyrene patch generates static electricity from wind, could run ACs | This energy harvesting is enabled by electrospinning alternating layers of small and large diameter polystyrene fibers.


The innovative thin patch, made from multiple layers of polystyrene each around one-tenth the thickness of a human hair, produced static electricity.

Researchers claimed that the innovative thin patch, made from multiple layers of polystyrene each around one-tenth the thickness of a human hair, produced static electricity. Published in Advanced Energy and Sustainability Research, the study describes the upcycling of expanded or foamed PS waste into electromechanically responsive triboelectric laminates (TLs). This energy harvesting is enabled by electrospinning alternating layers of small and large diameter polystyrene fibers, which upon friction establish an effective dipole moment within the TL, according to researchers.
