Recently, smartphone companies have been trying to make their devices more attractive to consumers by offering beautiful body color options. In addition, sometimes you can find smartphones trimmed with leather, precious metals, and even devices with transparent panels. However, Vivo has gone the furthest by introducing a technology that allows the user to customize the color of the smartphone case.
The technology shown by the Chinese company is based on electrochromism. This is a phenomenon that allows glass to change color and transparency when an electrical voltage is applied. It is worth noting that electrochromatic glass is not something completely new. It is used in the manufacture of smart windows for cars and buildings.
Roughly speaking, this is a sandwich of two glass plates, two transparent electrode sheets with an electrochromatic film between them, as well as an ionic conductor and an ionic film. When current is applied, the ions change their consistency, affecting the refraction of light, thereby showing different colors.
The smartphone on which the technology was demonstrated was carefully disguised, but it is very reminiscent of the Vivo S7 5G. It is worth noting that the technology is characterized by extremely low power consumption, so it will not contribute to the heating of the smartphone and the rapid discharge of the battery. In addition, since the electrochromatic glass itself is transparent, it provides even more personalization options.
