The invention belongs to the technical field of sensors, and provides a static and dynamic three-dimensional microcrack propagation sensor preparation method, a sensor and equipment. The preparation method comprises the following steps: preparing a piezoresistive / piezoelectric sensing functional material dispersion material, and attaching the piezoresistive / piezoelectric sensing functional material dispersion material to the surface of a
fiber cloth matrix to obtain piezoresistive / piezoelectric sensing
fiber cloth; performing pre-stretching treatment on the piezoresistive / piezoelectric sensing
fiber cloth to obtain piezoresistive / piezoelectric sensing three-dimensional microcrack fiber cloth; carrying out
microwave ablation on the piezoresistive / piezoelectric sensing three-dimensional microcrack fiber cloth, and removing a fiber cloth matrix to obtain a piezoresistive / piezoelectric sensing three-dimensional microcrack functional skeleton; the two faces of the piezoresistive / piezoelectric sensing three-dimensional microcrack functional framework are coated with conducting
layers correspondingly, and then electrodes are formed; carrying out polarization treatment on the piezoresistive / piezoelectric sensing three-dimensional microcrack functional skeleton with the
electrode formed on the surface; and packaging the piezoresistive / piezoelectric sensing three-dimensional microcrack functional framework to obtain the static and dynamic three-dimensional microcrack propagation sensor.
