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.
