Abstract: A weight management mat for passively and automatically monitoring weight for one or more individuals in a household. The weight management mat generally includes a housing having an upper mat and a lower mat between which is sealed a pair of perpendicular sensor arrays. Each sensor array includes fiber optic cables laid out in a grid pattern. One or more microbend inducers act to induce detectable microbends in the fiber optic cables when an individual steps on the upper mat. The change in light intensity caused by these microbends is recorded by photodetectors and processed by a microcontroller. The present invention may be utilized to identify each unique individual stepping on the present invention by the pressure map of their feet. Thus, recorded weight measurements may be tracked to aid in weight management.
