[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] A method for preparing a microstructured piezoelectric sensor based on micro-stereolithography, comprising the following steps:
[0026] The first step, the preparation of the soluble mold 3: put the soluble photosensitive resin 4 into the resin tank 5, adjust the lifting of the printing platform 2 immersed in the soluble photosensitive resin 4 to control the thickness of the printing layer, and use the ultraviolet light 1 to expose for layered curing and print The layer thickness is 0.04mm, the bottom layer is 1-3 layers, the exposure time of the bottom layer is 6s, and the exposure time of the subsequent single layer is 1-2s, and the microstructured soluble mold 3 is prepared, such as figure 1 shown;
[0027] The second step, the preparation of the composite piezoelectric material 9: mixing and dispersing the piezoelectric material and the organic matrix, a...
