摘要
设计并制备了一种新型微力传感器。将光纤Bragg光栅(FBG)用聚氨酯封装成柱状,将其一端固定在外壳底板上,另一端和杠杆的一端固定,通过杠杆原理起到对微力的增敏作用。当作用力在0~1.666 N变化时,该传感器的灵敏度为0.952 nm/N,是裸光纤拉力灵敏度的3.81倍。通过改变杠杆比例可以使该结构满足不同的测量范围和灵敏度。
Design and fabricate a novel micro-force sensor.The fiber Bragg grating( FBG) is packaged into columnar by polyurethane,one end is fixed on baseplate of the shell and the other end is fixed with one end of lever,through lever principle,play a role of sensitization to micro-force.The sensitivity of sensor is 0.952 nm / N, when the force change is 0~ 0.1666 N,and it is about 3.81 times of the bare optical fiber tension.The structure can fit with different measuring ranges and sensitivities by changing ratio of lever.
