Orkan Telhan is an artist and professor at the University of Pennsylvania who has been dabbling with interactive media art for many years: from interactive glowing clouds, to singing dust, to psychotropic rocking-chairs – but now he is shedding light (pun intended) on luminescent, customizable printing.
To create the glow, Telhan prints designs on films with phosphor, a luminescent material that emits light when stimulated electrically. The electricity that passes through the film excites the electrons in the phosphorus, causing it to emit light. Telhan also demonstrates a similar phenomenon using electrochromic ink that instead changes the film’s opacity when electricity is applied. This technology is already being developed and sold as smart glass that become opaque with the flip of a switch. Both types of inks are available to the public for those that are scientifically savvy and wish to illuminate their creative designs.
