There are many creatures on our planet with more advanced senses than humans. Turtles can sense Earth's magnetic field. Mantis shrimp can detect polarized light.
Reviewed by Danielle Ellis, B.Sc.Nov 3 2023 Elephants can hear much lower frequencies than humans can. Butterflies can perceive a broader range of colors, including ultraviolet light.
Small variations We've taken inspiration from the visual system of butterflies, who are able to perceive multiple regions in the UV spectrum, and designed a camera that replicates that functionality. We did this by using novel perovskite nanocrystals, combined with silicon imaging technology, and this new camera technology can detect multiple UV regions." UV light is electromagnetic radiation with wavelengths shorter than that of visible light .
Related StoriesBeyond the increased number of photoreceptors, butterflies also exhibit a unique tiered structure in their photoreceptors. To replicate the UV sensing mechanism of the Papilio xuthus butterfly, the UIUC team has emulated the process by combining a thin layer of PNCs with a tiered array of silicon photodiodes.
