1. A pressure sensing device comprising:

  • a laser light source for producing a laser beam;

    a control component connected to said laser light source for controlling activation or deactivation of said laser light source;

    at least one section of optical fiber, configured to receive at least a portion of said laser beam and transmit at least a portion of said received laser beam within said optical fiber;

    at least one optical coupler;

    at least one sensor component, said sensor component configured to sense escaped light from said optical fiber; and

    a photodetector, said photo detector configured to receive a signal originated from said sensor component and transmitted to said photodetector via said optical coupler;

    whereby said signal provides data for determining pressure exerted on said sensing device.
