Skin-Like Electronics for Perception and Interaction: Materials, Structural Designs, and Applications

Recent advances in the material and structural design of skin-like electronics have enhanced the interactions between the virtual and physical worlds and between people and objects. Herein, the existing flexible sensing materials and microstructures, including flexible stimuli-responsive materials and response- and stretchability-enhanced microstructures, are reviewed. Five typical skin-like electronics with sensitivities analogous to the human senses (olfactory, visual, auditory, tactile, and gustatory senses) and their corresponding applications (gas, light, chemical composition, sound, and mechanical signal monitoring) are introduced. Finally, it is concluded with some perspectives on challenges and opportunities for future research in flexible hybrid electronics.
