The smart bed is modeled as an elastic mattress core, which supports a fiber optic sensor cable.
The initial and deformed geometries of the bed due to the body weight of the patient are
calculated using MSC/NASTRAN for a given body pressure. The deformation of the fiber
optic cable can be extracted from the deformation of the mattress. The performance of the
fiber optic sensor for any given placement is further calculated for any given perturbation.
