Abstract
A system and method for detecting degradation of a fiber optic in a strap of a body-worn device that is removably attached to an appendage or other location of a person or animal. A fiber optic is embedded within the strap. A light source emits light energy through the optical interface and into the fiber optic and a light sensor receives and detects light energy from the fiber optic. If the light energy is not received and detected from the fiber optic, the light energy is increased until the light energy is received and detected or reaches a maximum light energy at which time tampering is declared. If the light energy reaches a pre-determined threshold which is less than the maximum light energy, it is declared that the body-worn device requires servicing.
