Abstract Opening new horizons for droplet‐based energy harvesters, electricity generators (DEGs) face several obstacles, such as deficient current output and vulnerability to the external environment. In this study, a multigenerator (DEMG) subserved by an electromagnetic generator (EMG) is proposed tackle them. By introducing mechanical buckling‐induced 3D structure, DEMG designed have sufficiently high figure of merit flexibility/elasticity harvest electric from droplets. Thanks hybrid effect EMG, total amount induced charge enhanced more than 8809% compared with that DEG only. Furthermore, continuous supply expected even under dusty humid conditions. This study not only provides pathway overcome inherent limitations conventional DEGs but also paves way efficient droplet harvesting technologies applicable in diverse environmental

Опубликована: Сен. 10, 2024

Abstract Droplet‐based electricity generators (DEGs) have emerged as innovative devices capable of transducing the kinetic energy falling water droplets into electrical power, thereby presenting a promising solution for ambient harvesting. For effective application, DEGs must exhibit transparency and flexibility to facilitate aesthetic integration optical/mechanical adaptability utilization on natural objects wearable devices. In this study, hydrogel‐based DEG (Hy‐DEG) designed is proposed be seamlessly integrated everyday environments without compromising design or functionality. With intrinsic characteristics hydrogel, Hy‐DEG exhibits superior optical transmittance (≈99%) stretchability (≈70% its original length), generating output performance ≈45 V voltage, 15 µA current, 42 µW maximum peak with single droplet impact. This capability can operate electronic environmental monitoring while maintaining seamless commonly encountered surfaces. context, study elucidates hydrogel bestowing novel functionalities upon DEG, expanding potential harvesting in residential commercial contexts. The implications research extend beyond conventional generation, fostering development self‐powered, transparent, flexible

Development of Multi Droplet-based Electricity Generator System for Energy Harvesting Improvement from a Single Droplet

Functional Composites and Structures, Год журнала: 2024, Номер 6(3), С. 035009 - 035009

Опубликована: Авг. 29, 2024

Abstract Due to high output performance, the droplet-based electricity generator (DEG) is garnering attention as a promising alternative power source for small electronic devices. Accordingly, utilize DEG source, efforts boost have focused on methods modify material modification and introduce surface structure. However, behavior feature that reconfigured droplet falls after operation leaves room one more energy harvesting from single droplet. Here, multi system (MDEG) constructed with multiple units proposed harvest The continuous movement of water realized through inclined stair structure MDEG, resulting in electrical generation many times it falls. In particular, 2-step MDEG consisting two can 45% higher performance than DEG. Therefore, this study implies contribution development DEGs by considering dynamics, which has been overlooked existing studies.
