Organic Photodetector Inspired By Mantis Shrimp Eyes

A new kind of organic photodetector small enough to fit on a smartphone but capable of hyperspectral and polarimetric imaging gets its inspiration from the eyes of mantis shrimp.

The creators of the new organic photodetector got their inspiration from the eyes of mantis shrimp, which are exceptionally good at accurately capturing subtle gradations of color. So, the researchers created an organic electronic sensor that mimics the mantis shrimp’s eye. It’s called the Stomatopod Inspired Multispectral and POLarization sensitive (SIMPOL) sensor. And, yes, stomatopod is the fancy name for mantis shrimp.

The researchers developed a prototype SIMPOL sensor that can simultaneously register four spectral channels and three polarization channels. In comparison, the charge-coupled devices used in smartphones have only three spectral imaging sensors, which detect red, green, and blue; and only two polarization channels. In addition, the SIMPOL prototype can measure the four color channels and three polarization channels at one point, whereas CCDs rely on imaging sensors spread across several points.
