The extraordinary properties of biological materials often result from their sophisticated
hierarchical structures. Through multilevel and cross-scale structural designs, biological …

Biologically inspired artificial vision research has led to innovative robotic vision systems
with low optical aberration, wide field of view, and compact form factor. However, challenges …

Conventional wide-field-of-view cameras consist of multi-lens optics and flat image sensor
arrays, which makes them bulky and heavy. As a result, they are poorly suited to advanced …

Metal halide perovskite, an emerging photosensitive semiconductor, has been widely
employed in solar cells, light‐emitting diodes, photodetectors, and lasers owing to its …

We report a new microfabrication method of multifocal microlens arrays (MF-MLAs) for
extended depth-of-field (DoF) using multilayer photolithography and thermal reflow …

Compound eyes found in insects provide intriguing sources of biological inspiration for
miniaturised imaging systems. Here, we report an ultrathin arrayed camera inspired by …

In the natural evolutionary process, biological creatures have developed diverse visual
structures apt for their habitational environments. These natural vision structures have …

Luminescence is an essential signal for many plants, insects, and marine organisms to
attract the opposite sex, avoid predators, and so on. Most luminescent living organisms have …

Nature has developed a wide range of functional microstructures with optimized mechanical
properties over millions of years of evolution. By learning from nature's excellent models and …
