This article presents a bioinspired, self-powered, hemispherical retinomorphic eye (SHRE) with an ionogel heterojunction retina. The SHRE is designed to mimic the biological eye, capable of wide-field detection, efficient visual signal processing, and retinal transplantation. The photoreceptors are made of ionogel heterojunctions, which exhibit broadband light detection (365 to 970 nm), a wide field-of-view (180°), and photosynaptic behavior (paired-pulse facilitation index: 153%). The ionogel heterojunctions are driven by the photothermoelectric effect, enabling self-powered operation. The retinal photoreceptors are transplantable and conformal to complex surfaces, making them suitable for visual restoration and dynamic optical imaging. The study demonstrates the SHRE's ability to perform neuromorphic imaging and motion tracking, showing its potential for applications in artificial vision and robotics.This article presents a bioinspired, self-powered, hemispherical retinomorphic eye (SHRE) with an ionogel heterojunction retina.
