Claim:
1. An optical fiber sensor device, comprising: a sensor plate formed of a deformable or elastic material and structured to include a 1-dimensional array of holes that are at different locations and penetrate through the sensor plate; a length of polarization maintaining (PM) fiber as a sensing element and engaged to the sensor plate by sequentially passing through the holes at multiple engaging locations on the sensor plate so that different sections of the PM fiber are alternatively on opposite sides of the sensor plate and two adjacent PM fiber sections are on opposite sides of the sensor plate to form sensing locations; an optical light source that produces probe light and is coupled to the PM fiber to deliver the probe light into the PM fiber; and a detector module coupled to receive probe light from the PM fiber and to measure the received probe light to determine a stress exerted on the sensor plate.
