About

Chi-Yuan Chang is a leading researcher in the fields of flexible photonics and laser technology, with a particular focus on stretchable and transferable optoelectronic devices. His most cited work, “Highly Stretchable Label‐like Random Laser on Universal Substrates” (2016), has garnered 36 citations and represents a significant breakthrough in the development of random lasers. Chang’s major contribution lies in engineering a label-like random laser that can be integrated onto virtually any substrate—flexible, curved, or rigid—while maintaining high performance and stretchability. This innovation overcomes traditional limitations of laser fabrication, enabling mass-producible, low-cost, and versatile light sources with inherent advantages such as simplicity and flexibility. Beyond the core laser design, his work demonstrates practical applications in temperature sensing, showcasing the device’s multifunctionality. By merging the principles of random lasing with wearable and label-like formats, Chang has opened new pathways for smart sensors, flexible displays, and biomedical diagnostics. His research continues to inspire advances in soft photonics, making him a notable figure in the push toward next-generation, universally adaptable optical systems.
