a Anatomy of an octopus eye and biomimetic SHR-E eye with ionogel photoreceptor (SHR-E: self-powered hemispherical retinomorphic eye, PPy-NPs: polypyrrole nanoparticles, TFSI-: bis(trifluoromethanesulfonyl)imide anions, HBA, 4-Hydroxybutyl acrylate, EOEOEA: 2-(2-Ethoxyethoxy) ethyl acrylate). b Schematics of our hemispherical retina with neuromorphic signal processing from ionic heterogel pillarforest. c Process mechanism of optical-to-electrical converter (E: electric potential). d Photographs of the hemispherical retina with multicolor light exposure, high surface conformal and stretchability.
