Hydrogel-Based Droplet Electricity Generators: Intrinsically Stretchable and Transparent for Seamless Integration in Diverse Environments (Adv. Funct. Mater. 9/2025)

Abstract

Hydrogel-Based Droplet Electricity Generators

In article number 2411350, Younghoon Lee, Dongwhi Choi, and co-workers introduce the hydrogel-based droplet electricity generator (Hy-DEG), distinguished by outstanding transparency (99.2%) and stretchability (70%). These attributes facilitate seamless integration into everyday substrates without compromising electrical performance. Notably, Hy-DEG maintains stable energy generation even under bending conditions, demonstrating its robustness and suitability for diverse applications.
