Optoelectronic skin is a research concept and technological approach focused on developing flexible and stretchable electronic systems that integrate optical and electrical functionalities, inspired by the sensory properties of biological skin. This field investigates the design, fabrication, and integration of novel materials and device architectures capable of detecting and responding to external stimuli, such as light, pressure, and temperature, often exhibiting high sensitivity and compliance. Its significance lies in enabling advanced sensory capabilities for applications including soft robotics, biomedical devices, and human-computer interaction, facilitating more intuitive and adaptable interfaces.
