Year: 2024

Type: article

Abstract: The accelerated evolution of a diverse array of miniature sensors and Internet of Things (IoT) technologies has resulted in a surge in demand for decentralized continuous power supplies. A substantial body of research has been conducted into a range of small-scale energy conversion devices. Among these, water evaporation-induced power generation devices, as a recently developed technology, have considerable scope for improvement in their electrical output performance. A flexible water evaporation-induced power generation device based on melamine foam has been developed. The device is capable of generating a voltage of 0.6 V and a current of over 40 µ A in natural conditions. The device's flexibility enables it to maintain a voltage output capacity of over 0.5 V even when deformed. Furthermore, the device exhibits enhanced photothermal conversion efficiency, which in turn elevates the evaporation rate under outdoor illumination. The enhanced evaporation rate under light conditions enables the device's current output to exceed 60 μ A. This work achieve the enhanced power generation performance of water evaporation-induced power generation devices in natural environments, thereby expanding their potential applications.
