Photoresponse ionic gels can detect light as a photoreceptor to emulate biological vision for artificial retina and skin. However, the existing ionic gel\u2010based photosensors face limited response speeds and detecting sensitivity due to inefficient ion transport. Here, a high\u2010performance elastomeric photodetector made of polyvinyl alcohol\u2010based pyroelectric eutectogels, containing polar ions and crystalline domains, is reported, which exhibits a high pyroelectric coefficient and enables efficient optical\u2010to\u2010electrical conversion via spontaneous polarization, even under 30% tensile strain. The resulting self\u2010powered photodetector features a broad spectral response spanning 365\u20131300\u00a0nm, with photoresponsivity, detectivity, and response time of 42.06\u00a0mA W\n                    <jats:sup>\u22121<\/jats:sup>\n                    , 7.65 \u00d7 10\n                    <jats:sup>10<\/jats:sup>\n                    Jones and 24\/35\u00a0ms at 455\u00a0nm, respectively.
