Abstract: Electronic device for the automated painting and drying of fingernails, which allows the user to choose the color they want to paint the nails as well as to carry the device due to its light weight. In one embodiment, the device has a sensor that identifies the hand that has been introduced in it and activates the activation of the device, a touch LED screen, which allows the user to choose the nail and color with which to paint it, without the need for specialized personnel to operate it, as well as to inform the user through visible and audible means the process taking place. In one embodiment, the unit contains capacitive and infrared sensors to detect the difference of the surface of the finger and nail, a computer or processor which guides and controls the paint head with the ink that carries the staining of the surface of the nail. In one embodiment, a device expels air towards the nails and then applies a beam of ultraviolet light for rapid and uniform curing/drying.
