The researchers created a bio-inspired device that mimics the functions of red, green, and blue photoreceptors as well as the neural network responsible for early visual processing by drawing inspiration from the extraordinary design of our own retinas.

What the Human Eyes See is Reproduced

The idea for their invention was inspired by nature, according to Kai Wang, an assistant research professor in the Department of Materials Science and Engineering at Penn State.

The vibrant world we can see is the result of this natural process. The scientists created a sensor array utilizing narrowband perovskite photodetectors that closely resemble the cone cells in our eyes in order to replicate this complex system in an artificial device. They attached this sensor array to a neuromorphic algorithm that was created to mimic the functionalities of the neural network, enabling the processing of data and the creation of high-quality photographs. The core of cameras and other optical technology, photodetectors are essential for transforming light energy into electrical impulses.

According to the researchers, the use of perovskite materials in the gadget allows for the creation of electricity by light absorption, potentially opening the door for battery-free camera technology. The device's structure is similar to that of solar cells, according to Luyao Zheng, a postdoctoral researcher at Penn State, and it produces electricity when exposed to light.

Additionally, this study has the potential to enhance artificial retina biotechnology, opening the door to the possibility of replacing harmed or dysfunctional cells in the eyes in order to restore eyesight.
