Abstract

Ultra-flexible organic optoelectronic devices are transforming the landscape of futuristic biomedical and wearable applications, especially within the Internet of Things realm. The notable flexibility of organic materials, combined with their affordable and efficient processing, is driving the rapid development of flexible electronics. However, to fully harness these next-gen, human-friendly wearables and sensors, further exploration into improving their electronic functionality and mechanical durability is essential. In this presentation, recent breakthroughs and ongoing challenges in ultra-flexible organic electronics will be reviewed. The initial results from selecting suitable materials and engineering structures will be discussed, aimed at creating energy harvesters and sensors that are skin-compatible. These devices must retain their photonic and electrical efficiency, even under external mechanical pressures. By sharing our research, we hope to encourage more studies that will expand ultra-flexible electronics across various fields, such as wearables, primary healthcare, medical applications, and AR/VR motion recognition. Our continued research and innovation can lead to seamlessly integrating cutting-edge electronics into daily life, enhancing human well-being and pushing the limits of technological advancements
