NOVELTY - One of bridge health monitoring sensor, comprising insulation shell, data processing unit and sensor on the insulation shell and sealing, then data processing unit through data transfer using pin the lower part unit connected with sensing element, said sensing element is embedded part, comprising one of pressure sensitive element, the pressure sensitive element and signal collecting terminal is one of semi-sphere pressure sensitive element, and wherein the pressure sensitive element is semi-sphere forming with one outer side and one pressure sensitive element is concentric hemispheroid and provided with the same and hemispherical contact face, between the hemispherical contact face and semi-sphere pressure sensitive element there is a gap, and wherein the gap and fill with silicon pressure sensitive glue, in addition, wherein the silicon pressure sensitive glue and the concentric semi-sphere between also formed with one layer of graphene nano sheet. This new utility model improving of sensor performance, can effective improve sensitivity and use life of sensor, and especially suitable for embedded for health monitoring for and on the bridge body.
