Abstract
A structure displacement self-powered sensor based on the post-buckling piezoelectric effect comprising an upper unit, a lower unit, a traction system and an information transmission system. The upper unit is slidably connected with the lower unit; the upper unit includes an upper deformable plate and an upper piezoelectric film bonded to the upper deformable plate; the lower unit comprises a lower deformable plate and a lower piezoelectric film bonded to the lower deformable plate; when the upper deformable plate and the lower deformable plate are deformed, a voltage signal is generated and transmitted to the information transmission system through the data acquisition unit. The present disclosure can monitor the settlement of the pier or the expansion or contraction in the expansion gap of the structure by monitoring the output voltage of the equipment. The present disclosure is self-powered and can work for a long time, normally with minimal maintenance.
