▎ 摘　　要

NOVELTY - Piezoelectric-triboelectric product based on multi-material printing technology comprises piezoelectric layer and a conductive layer stacked to form a layered structure, and the piezoelectric layer and the conductive layer have at least one layer. The piezoelectric layer is composed of composite ink material A. The composite ink material A mainly includes solvent and 500-200 pts. wt. double component addition type liquid silicone rubber, 500-800 pts. wt. piezoelectric ceramic filler. The conductive layer is composed of composite ink material B. The composite ink material B mainly includes solvent, 950-800 pts. wt. double-component addition type liquid silicone rubber, and 50-200 pts. wt. carbon-based conductive filler. The piezoelectric-triboelectric product is obtained by writing three-dimensional printing with multi-material ink. USE - Used as piezoelectric-triboelectric product based on multi-material printing technology. ADVANTAGE - The method improves the polarization efficiency of piezoelectric composite materials, breaks through the problems of poor dispersion and weak performance of the traditional simple blending of piezoelectric ceramics/polymers/conductive filler ternary composite materials, uses three-dimensional printing technology to form a three-dimensional network structure product, reduces the compression modulus of the product, improves the polarization efficiency of the material, and increases the electromechanical coupling ability of the product. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a preparing the piezoelectric-triboelectric product based on multi-material printing technology; a voxel-structured piezoelectric-triboelectric product based on multi-material printing technology,
