Abstract (EN): Triboelectric nanogenerators are a new promising energy harvesting technology that has a simple working mechanism, produces high output power and has the ability of harvesting energy from a wide range of sources and under various conditions. Here, we present a rotary triboelectric nanogenerator (TENG) that harvests energy from water flows using polytetrafluoroethylene (PTFE) and Nylon 6.6 as triboelectric materials. The operation mechanism of the fabricated rotary TENG is a hybridization of the contact and sliding modes by using the triboelectrification and electrostatic induction effects. The optimization of the developed setup for the effective generation of electricity showed that the best configuration consists in a triboelectric structure with four Nylon and one PTFE plate for the maximum used water flow of 44 L/min. With this configuration, the rotary TENG delivers a mean voltage value of similar to 102.2 V, a short-circuit current density similar to 120 mA/m(2) and a maximum power density of similar to 6.1 W/m(2). Finally, with this device it was possible to light up more than 50 serial connected light emitting diodes, fully charge a 1.0 mu F capacitor with 15.2 V in just 65 s and feed a commercial temperature and humidity sensor. The developed rotary TENG can then be applied to autonomous sensors that monitor water supply systems using the energy produced by water movement in plumbing.
