1. A security system, comprising:

  • an energy harvesting element arranged on a body structure;

    a sensor device powered by electrical energy generated by the energy harvesting element, the sensor device generating a sensor output signal according to a sensed parameter measured by the sensor device; and

    an energy transmissive layer arranged over the energy harvesting element on the body structure and arranged over the sensor device, the energy transmissive layer having a body-facing side facing a surface of the body structure, and an energy-incident side opposite the body-facing side,the energy-incident side presenting an opaque appearance when viewed from substantially any aspect on the energy incident side, andthe energy transmissive layer passing 50% or more of light energy impinging on the energy transmissive layer through the energy transmissive layer to activate the energy harvesting element.
