Random lasers have abundant inherent advantages compared to conventional laser, such as flexibility, size, cost, simple design, and mass production. It has been the hot research topic in recent decades. An integrated random laser label with transferability, flexibility, and temperature sensing is created and demonstrated in this work. The highly stretchable label‐type random laser (HSRL) can not only function stably under 100% strain with at least 500 times test but can also be easily transferred on arbitrary substrates irrespective of the material being rigid, flexible, nonplanar, or rough. In addition to features mentioned above, random laser signals can be stimulated and controlled repetitively within human body temperature. This shows great potential that the HSRL can serve as photonics modules for further advanced developments of a variety of applications covering many different fields, such as wearable systems, robotic sensors, and stretchable information communications.
