One of the latest examples of biomimicry is copying the moth’s eye.
Researchers Florent Boudoire and Artur Braun at EMPA, the Swiss Federal Laboratories for Materials Science and Technology, made a breakthrough by examining how effectively the moth’s eye makes use of light.
According to an EMPA report:
“Empa researchers have developed … a photoelectrochemical cell, recreating a moth’s eye to drastically increase its light collecting efficiency. The cell is made of cheap raw materials – iron and tungsten oxide.”
