The future concept for smart factories is directly correlated to the development of smart sensor concepts. Here photonic sensors can lead to considerably higher flexibility, user-friendliness and efficiency in automation, robotics, optimizing individual machine processes or human machine interaction. Integration of communication with sensors and actuators on the lowest field level provides a complete and consistent flow of information within the entire automation pyramid. Fiber optics enable guiding information and in combination with fiber embedded sensors (Lab-in-a-fiber) a simple sensor network can be established that fulfills the above mentioned requirements. Such concept allows completely new possibilities for gesture control in combination with smart glasses (augmented reality) to provide safe working places in harsh industrial environment but also supports workers at production lines with respect to ageing society. Different concepts will be described and discussed for various industrial applications.
