Abstract
Lead halide perovskites, known for their excellent performance in optoelectronic devices, are explored for their potential in optoacoustic transducers. The authors leverage the material's high absorption coefficient, low specific heat capacity, and small thermal diffusion coefficient to achieve record-high performance in optoacoustic transducers, surpassing existing technologies. Miniaturized devices are fabricated on fibers, demonstrating high-resolution ultrasound imaging capabilities.
