Abstract
Systems, methods, and other implementations described herein relate to a manner of detecting kinking or other bending on a bendable structure. In one implementation, a bendable structure is configured to kink at different locations. First and second sensors surface-mounted antiparallel along the bendable structure have bending responses that increase with increasing amounts of bending, and that are increasingly sensitive along their lengths. The bending responses from first and second sensors are received at a first time and a second time subsequent to the first time. The formation of a kink is identified in response to identifying that the bending responses are indicative of unkinked bending at the first time and indicative of kinked bending at the second time. In response to identifying the formation of the kink, the location of the kink is identified based on the bending responses at the first time.
