Devices for monitoring structural health conditions of host structures. A device includes at least one optical fiber sensor and an electronic module. The optical fiber sensor includes a rolled optical fiber cable operative to generate a frequency shift of a light signal passing therethrough and a coating layer applied to the rolled optical cable. The frequency shift is commensurate with vibration of the host structure. The electronic module sends an input light signal to the optical fiber sensor, receives a sensor signal from the optical fiber sensor, and processes the sensor signal.
