摘要: We designed a stable triboelectric generator (TEG) consisting of new combination poly(vinylidene fluoride) (PVDF) and polyethylene (PE) films which shows prospect for easy low cost device fabrication. Both PE PVDF are selected from the negative side series considering difference in charge affinity. An open circuit peak-to-peak output voltage ∼20 V current density ∼0.34 A m−2 were obtained just by striking TEG manually. The effect directional forces on was studied future anisotropic pressure sensor fabrications. charging capacity checked using commercially available capacitor revealing battery charging. Furthermore, powered at least 12 commercial white light emitting diodes indicates its potential use as carbon emission free power source suitable portable electronic devices.
