China s fiber optic torque sensor
This sensor comprises a torque-sensitive bending structure and two diagonally arranged optical fibers, incorporating an embedded fiber Bragg grating sensor. In this paper, we propose and demonstrate experimentally an optomechanical torsion sensor using a microfiber mechanical resonator. Quadrants of photoelectric sensors are employed to capture minute deformations induced by torque on the rotational axis, converting them into measurable voltage. The invention discloses a fiber sensing device for sensing torque parameters, comprising a helical shell, a plurality of A-sided distortion teeth and a plurality of B-sided distortion teeth, wherein the A-sided distortion teeth and the B-sided distortion teeth are continuously arranged at two.
