Electronic cosmetic
The electrochromic nail is made up of a number of layers sandwiching transparent conducting oxides, a number of electrochromic polymers to make the various colours, ion-storing polymers to maintain the colours and an electrolyte which enables ionic interchange between the different polymers.
A digital control device programmes the colours and makes modifications as desired. The device includes an image-capturing digital system that can select the desired colour of any particular surface, a screen to visualise the settings selected before application as well as electrodes to interface the device with the electrochromic nail and thus effect the colour changes.
The author has presented a patent for the invention (P-200101682). The same system could be used to colour more general surfaces.
