Skin is the body's largest organ, and can feel thetemperature, humidity, pressure, and external complex stimuli. Recreatingthe properties of human skin through an electronic system (electronic skin)is a hot topic in research with a wide range of applications in artificialintelligence, robots, and man–machine interfaces. In order to mimic humanskin's sense of touch, researchers use different transmission mechanisms and structuraldesigns to develop a flexible, stretchable, high-sensitivity, and high-resolution sensor array. High-density flexible circuit integrationtechnology, wireless technology, and self-powered technology make theelectronic skin portable and removable. Self-healing technology enables theelectronic skin to be repaired from accidental scratching to compensate fordevice function. This review mainly covers the latest domestic and foreignmaterials, devices, and advanced technologies used to improve the performanceof electronic skin to imitate the perception of skin and generate bionicsignals.
