Would you like to have a bionic eye? You may want to consider this new device that uses perovskite cells and an artificial neural network to function almost like the human eye.
, you first need to know how the real human eye enables us to see things. Your eyes have a layer of light-sensitive tissues called a retina. All objects you see emit light that enters your eyes and falls on that retina.
The device from the PSU team works in almost the same exact fashion but uses artificial components. Light enters the device through a lens, which is then captured by narrowband From perovskite cells, the light reaches the artificial neural network that employs neuromorphic algorithms — special computer programs that are capable of mimicking the human brain’s ability to turn electrical signals into images. Finally, the device produces the image of the object.Interestingly, the perovskite photoreceptors used in the device shares functional and structural similarities with the perovskite cells used in solar panels.
