Progress and Potential
Mechanoluminescence (ML) is a fascinating emission phenomenon involving the transformation of mechanical energy to visible light. Although the first recorded discovery of ML was in the 17th century, the intrinsic mechanism has remained obscure for many years. With deeper understanding of the inherent mechanism, many pure organic ML luminogens have been developed. The clearer this inherent mechanism of ML material has become, the more eager we are to explore the value of its potential application. Here, an ML material is shown to exhibit bright ML emission by mechanical stimulation even under daylight. More excitingly, the quantitative relationship between force pressure and ML intensity has been obtained by devices based on ML material (tPE-2-Th). The wearable ML device shows potential for future application of electronic materials for communications, information storage, and health care, thus leading to improvement of our daily lives.
