1-12. (canceled)
A spring comprising:
- a composite structure comprising reinforcement fibers within a matrix,
- wherein the composite structure comprises at least one Bragg cell and at least one optical fiber connected to the Bragg cell.
A method for measuring a load on at least one wheel of a vehicle, the method comprising:
- a) installing at least one optical fiber with Bragg cells, forming a sensor for measuring deformations and comprising the Bragg cells, in a spring;
- b) emitting, by a source module, light signals toward each Bragg cell;
- c) each Bragg cell returning a light signal to a receiver module;
- d) converting, at the receiver module, the light signals into output data and transmits the output data to a processor module;
- and
- e) processing, at the processor module, the output data and calculating the load on the wheel equipped with the spring.
