Starch Cross-Linked Glass Fibers for Water Evaporation-Induced Electricity Generation
Water evaporation-induced electricity devices (WEDs) have become extremely attractive, converting ambient heat into electricity while being environmentally friendly. However, most current WEDs are costly and cumbersome to fabricate, which greatly limits their commercialization process. Here, we present WEDs based on starch cross-linked with glass fiber filter paper (Starch-GF). A single device produced an open-circuit voltage of 0.3 V, a short-circuit current of 1.2 μA, and a maximum power density of 1.8 mW/m<sup>2</sup> in a natural environment under 24 h of continuous measurements. Starch-GF devices can drive electronics after charging capacitors and have environmentally friendly properties. This research contributes significantly to the discovery of hydrovoltaic materials and their practical implementation in hydrovoltaic devices.
