ConspectusPiezoionic skin sensors are one kind of artificial electrical that can output sensing signals in response to external strain or stress stimulus with merits flexibility, lightness, scalability, and high sensitivity. They have been emerging as an important platform intelligence, such smart healthcare, bionic robotics, microelectromechanical systems. Piezoionic typically composed electrolyte laminated symmetric electrodes based on ion migration redistribution under a gradient field. However, existing challenges significantly impede the performance piezoionic sensors, including low electromechanical coupling efficiency electrode materials, instability strain-induced interface separation sensor interfaces. In recent years, our group collaborators made attempts addressing as-mentioned critical order achieve flexible satisfying for wearable applications. First, we developed various materials highly efficient storage transfer, graphdiyne, quinone composites, graphitic carbon nitride. These present superior mechanical properties enhanced efficiency. Second, improve stability electrolytes, especially air environment, ionogel electrolytes instead conventional hydrogel electrolytes. Ionogels contain stable ionic liquids, which effectively devices preserved even after several months. Third, regard separation, engineered material interfaces elaborate structures. The as-designed tree-root-inspired show conditions, display negligible deterioration thousands bending cycles ambient environment. Finally, obtained studied their practical applications, electronics, health monitoring, detections. For example, realized accurate detection blood pressure out-of-plane mechanism. This innovative technique completely avoids cuff issue commercial sphygmomanometers have. Moreover, multifinger-touch arrays effective braille recognition, potential eliminate communication barriers sight-impaired people. Human voices be easily differentiated by detecting vocal-cord vibrations captured obviously different patterns. is promising extended applied use virtual reality technology. Lastly, perspective highlighted set clear direction future research, low-cost synthesis, mass production healthcare products.
