Electronic skin is a multidisciplinary research field dedicated to developing flexible, stretchable electronic systems that mimic the sensory functions of biological skin. It investigates the design, fabrication, and integration of compliant materials and sensors capable of detecting and responding to external stimuli such as pressure, temperature, and strain. This concept is significant for advancing robotics, prosthetics, wearable technologies, and human-computer interfaces by providing artificial tactile and proprioceptive capabilities, enabling sophisticated interaction with the physical environment.
