A current is generated by airflow resonating the polytetrafluoroethylene (PTFE) film
Tiny generators that harvest light and wind energy together have been developed by scientists in China. This technology works 24 hours a day to generate power and could run sensors or LEDs, or even charge lithium-ion batteries.
Shrinking triboelectric generators into today’s tiny gadgets limits their output. Friction between two films within the device generates the power but when miniaturised, the wear of these electrodes hinders this process.
