Fully Printable Manufacturing of Miniaturized, Highly Integrated, Flexible Evaporation-Driven Electricity Generator Arrays.

ABSTRACT: Harvesting sustainable clean energy from natural water evaporation holds great promise to provide continuous power for portable and wearable electronics. However, poor portability and complex fabrication processes hinder the low-cost and large-scale integration of flexible evaporation-driven electricity generators (FEEGs). Herein, a fully-printed flexible evaporation-driven generator (PFEEG) is developed. Utilizing custom-formulated functional inks, the asymmetric structures, current collectors, and hygroscopic water storage units can be manufactured by a patternable, scalable, and layer-by-layer deposition technique of screen printing. Thus, a PFEEG unit (0.5 cm × 1 cm × 38 µm) can generate a voltage of ≈0.8 V over a wide relative humidity (RH) range from 20% to 90%, and a maximum power d
