Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reconstituted wood, in particular to a preparation method and device of intelligent piezoelectric sensing reconstituted wood. BACKGROUND

[0002] The piezoelectric sensor is a sensor based on piezoelectric effect, which is a self-powered and electromechanical conversion sensor. The sensitive element of the piezoelectric sensor is made of piezoelectric material. After the piezoelectric material is stressed, an electric charge is generated on the surface. After the electric charge is amplified by a charge amplifier and a measurement circuit and the impedance is changed, the electric charge becomes an electric quantity output proportional to the external force. The piezoelectric sensor is arranged in the reconstituted wood. During the use of the reconstituted wood, electricity can be generated by stepping on the wood. However, in the preparation process of the existing reconstituted wood, the same production line can only reconstitute single or a small number of wood, which is inconvenient to flexibly adjust the preparation size and inconvenient to adjust according to the size of the wood.
