An eye for an AI: Optic device mimics human retina

If our artificial intelligence is able to think like a human brain, why do we feed it data like a normal computer? Scientists are addressing this question by considering the sensory input we human receive and have developed an optical device inspired by the working of the human eye. Researchers in Oregon recently published findings of their optical sensor, which could make robotic components far more efficient. Using ultrathin layers of photosensitive perovskite material, normally adopted in solar cells, this device adapts its signals as it senses different intensities of light. Perovskites are chemical materials, composed of metal atoms carrying positive charges and oxygen or halide anions, carrying negative charges which layer into an interesting lattice.
