Abstract: Energy harvesting devices with great breathability facilitate continuous operation of healthcare applications and are the critical components in the self-power wearable microelectronic systems. However, the insufficient electric outputs largely diminish the effectiveness of generators as wearable power supply and the lack of moisture/thermal management causes discomfort in the practical electronic application. Herewith we report a self-powered and self-cooling fabric that enhances electric outputs and provides good wear comfort simultaneously, for the first time, by a synergistic effect of directional water transport and ion migration. The water evaporation on the fabric liquid diode with gradient wetting channels reaches 0.56 g·h − 1 for dehumidification, dissipating body heat with a temperature drop of 6.3°C for self-cooling. The devices deliver a DC current output of 0.40 mA·cm − 2 , twice that of devices without liquid diode and is sufficient to power a wide variety of practical wearable electronics.
