The invention discloses an anti-electromagnetic interference piezoelectric interlayer, comprising a piezoelectric sensor, an FPCB (flexible printed circuit board) and SMA (small A type) joints, wherein the piezoelectric sensor and the joints are connected with the FPCB by welding and cementing; sensing signals from the piezoelectric sensor are sent to the joints by a line on the FPCB; and the joints are connected with cables so as to send the signals to a signal processing center. By configuring the parallel wiring gaps of the FPCB, the arrangement of wire and the FPCB structure reasonably, the cross talk resistance and the radiated interference performance are realized. The anti-electromagnetic interference piezoelectric interlayer is used for solving the problem that a piezoelectric interlayer is subjected to electromagnetic interference easily in the use process and improving the stability and reliability of using the piezoelectric interlayer. The anti-electromagnetic interference piezoelectric interlayer can be applied to structural health monitoring widely.
