Electric-Fish-Inspired Thin Hydrogel Electrocytes Achieve High Power Density and Environmental Robustness.

ABSTRACT: Electric-fish-inspired hydrogel-based power sources offer a promising platform for powering soft, wearable, and implantable electronics due to their compliance, biocompatibility, and biodegradability. They typically consist of high- and low-salinity gel layers separated by anion- and cation-selective gel compartments, generating an electric potential that emulates the diffusion-based energy mechanisms of electrocytes in electric fish. However, their development has been hindered by high internal resistance, limited power density, and poor environmental stability. Here, a scalable layer-by-layer spin-coating strategy is introduced to fabricate hydrogel electrocytes with precise thickness control, yielding 106.1 µm-thick units comparable to biological electrocytes. This thin architecture sig
