A team of engineers has designed a new line of multicolored tattoo inks that switch on and off with different kinds of light. Described in a study published in Matter & Light, the technology could one day help people hide their tattoos when they have an important business meeting
A team of engineers has designed a new line of multicolored tattoo inks that switch on and off with different kinds of light. Described in a study published in Matter & Light, the technology could one day help people hide their tattoos when they have an important business meeting. They could even doodle on their own skin using a simple laser pointer.
