Retina-like sensors give machines better vision

Semiconductor-based devices that adapt to a wide range of light intensities could prove useful in self-driving vehicles and assembly lines.
Time courses of scotopic (top) and photopic (bottom) adaptation of MoS2 phototransistor array, for the pattern of ‘8’.

The number ‘8’ gradually becomes visible to a smart sensor as the device adjusts to dim (top) or bright (bottom) light. Credit: F. Liao et al./Nature Electron.

Smart optical sensors inspired by the human retina could improve artificial-vision systems used in autonomous vehicles and industrial manufacturing1.
