A bio-inspired vision sensor that can detect spectrally distinctive features

"in addition to detecting objects at night/ in shadows, can also handle smoke, fog, other strong light interference... collects data with minimal time latency, consuming very little power, small footprint... photodiode array arranged back-to-back with different spectral sensitivities, switchable between TiO2/Sb2Se3 shallow junction (enhances sensor's sensitivity to UV)/ Sb2Se3/Si deep junction (boosts sensitivity to visible wavelengths), very fast switching controlled through external bias voltage"
