Three-axis force visualizing system for fiberscopes utilizing highly elastic fabric

This paper presents a novel force sensing system for fiberscopes. The key features of the system are its low cost, high resolution, small size, and ability to measure three-dimensional force. A previous study described a novel force sensing system that could be attached to a very thin fiberscope, based on a force visualization mechanism utilizing panty stocking fabric - a highly elastic material. However, this system measures force in only one direction. In this paper, the system is extended to measure forces in any of three directions. The system is targeted for application to neurosurgical examinations. It may also be useful for other medical and non-medical examinations that involve the use of fiberscopes.
