Abstract Simulating the characteristics and achieving specific functions of biological systems are stirring but challenging. Developing biomimetic leaves (BLs) with such as photosynthesis, transpiration, solar spectrum similarity receives great attention. With increasingly developed hyperspectral imaging techniques, though BLs for have made significant strides, they still grappling low single function. In this review, first, tissue optical path natural analyzed. Then, spectral up‐to‐date pigments functional multifunctional summarized. The importance is highlighted. Notably, organic–inorganic hybrid vibrant colors multifunction, show boundless promise. At last, insights into perspectives challenges on provided. This review contributes profound materials toward plants.

Electronic skins (e-skins) are desired to perceive both the intensity and spatial distribution of applied pressures. Despite continuous progress in design high-performance individual pressure sensors, acquisition locational information pressures still mostly relies on preparation high-density sensor matrixes within e-skins, which dramatically increases device complexity hinders straightforward human-machine interaction. In recent years, integration optical visualization units e-skins has been raised as an alternative strategy for obtaining distribution. By utilizing pressure-induced light emission color change, could be visualized directly through distinct signals, eliminating necessity additional data processing display modules. this perspective, main strategies achieve introduced, including their mechanism, layout, materials, applications. The challenges prospects emerging field also discussed.
