碩士 === 國立臺灣海洋大學 === 光電科學研究所 === 107 === In recent years, with the prevalence of wearable components, making flexible and stretchable devices has become a popular topic of research. Flexible and stretchable components are of great interest with higher durability than ordinary rigid devices. Among these devices, the on-skin components of electronic skin have also been extensively studied. Since the electronic skin has the advantages of extremely thin and high biocompatibility, many studies have integrated various components onto the electronic skin to manufacture multiplexed skin components. Self-healing materials are the best materials for such on-skin devices. Since they can repair themselves after mechanical damages, the lifetime of the components can be significantly extended. Besides, to reduce the cost of maintenance, the damaged components do not need to be directly discarded, thereby reducing the burden on the environment. In this work, the Self-Healable Random Laser Photonic Skin（SHRLPS）demonstrated here combines self-healing materials and random laser components. The lasing threshold, intensity, and spectra of the device show the same performance under different tension and bending condition. This optical property allows the luminescence of the component to be unaffected by the deformation of wearing, with high comfort and adaptability. Besides, we also measure the optical properties of the device during the self-healing process. The result shows that the luminescence properties of the device are similar before and after self-heal. The self-healing process does not require external force stimulation, which makes it less susceptible to damage and significantly improve the durability of wearable components. In this work, the devices are flexible, stretchable, and highly durable, making this unique photonic skin extremely comfortable to wear. The random laser in the component can perfectly combine with the flexible substrate due to its cavity-free characteristics. Since the advantages of angle-free, high intensity, and narrow bandwidth, the red, yellow, and blue random lasers have great potential for Phototherapies such as anti-inflammatory, antibacterial, and anti-tumor. In this work, we also demonstrate possibilities of devices with phototherapy, display, and optical camouflage. It is believed that the invention of this new kind of light source can make up for the shortcoming of existing laser technology, and become a new generation of light source that integrates treatment, display, and aesthetics.
