Unlike existing incubators, NEOVUM does not work with blankets for darkening, as these often slide down and are extreme germ catchers. Electrochromic glass can be diffused and darkened by an applied circuit, even changing color to the soothing dark red imitating the womb. The darkening can be controlled individually for both longitudinal halves of the incubator via the touch slider, so that working on one side remains possible.
