Researchers have created a mechanical chameleon equipped with mechanical scales able to shift to almost any color in real-time.
Developed by a team from Wuhan University, the ‘chameleon’s’ scales feature a thin glass film set atop a sheet of indium tin oxide, which allows the scales to create electric fields. An array of nanodots was then etched into the glass and filled with gold bumps, followed by a layer of a silver-containing gel. Running an electric field through the scales will cause the amount of silver on the bumps to increase or decrease (as determined by the electricity’s polarity), and altering the size and shape of the bumps allows for the creation of any color (as determined by the device’s sensors).
