Nanomaterials-based Soft Optoelectronics: Advances in deformable QLEDs and E-Eyes

Recent advancements in soft electronics have garnered significant attention owing to their potential applications in personalized, mobile, and wearable electronic devices. However, conventional electronic/optoelectronic devices often face challenges due to mechanical mismatches with soft human tissues, resulting in issues such as device fracture under deformation and user discomfort. To address these challenges, ultra-flexible and stretchable electronic/optoelectronic devices with low system modulus and intrinsic softness have been developed. Here, our unique strategies for synthesizing nanoscale materials (e.g., quantum dots, silver nanowires), seamlessly integrating them into patterned arrays, and designing unconventional devices and systems to achieve flexible, foldable, and stretchable quantum dot light-emitting devices are presented. These deformable light-emitting devices can be integrated with stretchable biosensors to form standalone wearable systems, which can create various mobile consumer electronics applications. Recent progresses in soft robotic vision systems and their wearable-display-centric integration potentials can be also briefly discussed. These advancements in electronics/optoelectronics, which combine recent breakthroughs in nanoscale material technologies and unconventional soft electronics, open up many new opportunities.
