Researchers in England have developed a electric battery powered textile yarn that can be used to illuminate the clothes of jogger , cyclists , or outdoor workers for protection . This electroluminescent thread , or “ EL recital , ” is technically a multi - layer electroluminescent film composite material made from yarn and dipped in a special brightness level - emitting ink on the inside , with a insulated screening and a 2nd level of yarn on the outside . When electricity runs through the thread and ink , an galvanic field is created that illuminates any point where the out and inner layers of recital touch . of course , this would have a myriad of non - hardheaded United States , not the least of which would be draw more tending to the breasts of distaff order - goer .
