The utility model discloses an embedded sensor for road health monitoring and traffic dynamic monitoring. The sensor comprises a piezoelectric element and an interlayer gasket, substrates are arrangedat the upper end and the lower end of the piezoelectric element; a welding lug is integrally formed on one side of the substrate, a wire is welded to the welding lug, the number of the interlayer gaskets is two, four connecting pieces are integrally formed on the side faces of the interlayer gaskets at equal intervals, installation pieces are integrally formed at the other ends of the connectingpieces, spring grooves are formed in the middles of the opposite sides of the installation pieces, and springs are installed in the spring grooves. The mechanism is reasonable in design; the piezoelectric ceramic is used as a material of the piezoelectric element; the structure is simple, the reliability of traffic dynamic monitoring data is ensured, the sensor can also be used for health detection of the structure, the arranged structure composed of the interlayer gasket, the connecting piece, the mounting piece and the spring greatly improves the cyclic fatigue load resistance of the sensor,the service life of the sensor is effectively prolonged, and the use requirements can be well met.
