Whole-body, large-area tactile skin is well-cited as a requirement for emerging humanoids, prosthetics, and other robotic devices operating in unstructured environments. However, developing effective large-area tactile sensing skin has been elusive due to many complexities, particularly challenged by wiring and big data management, and remains a persisting issue. This review describes the challenges of large-area tactile skin and summarizes the recent progress in addressing the wiring and data m
