Vibrating wire sensors are widely used in the field of building monitoring.In particular

single-coil vibrating wire sensors are popular due to their simple design.However

when it is used for long-distance monitoring

sensors may suffer from the problem of reduction of output signal amplitude due to the influence of long distance cables.To address this issue

the structure of single-coil vibrating wire sensors is improved

and a dual-coil signal-enhanced vibrating wire sensor is designed.The feasibility of this design structure is verified through modeling using COMSOL software.Furthermore

through the fabrication and testing of actual sensor prototypes

comparative experiments are conducted.The experimental results show that this scheme can effectively enhance the signal strength of the sensors.
