Description

Technical field [0001] The present invention relates to the technical field of robotic touch simulation, and more particularly to a robot electronic skin analog tactile sensing device based on piezoelectric nano generator. Background technique [0002] The flexible piezoelectric nano generator prepared based on piezoelectric composite membrane is typically composed of piezoelectric filler and flexible matrix. When the piezoelectric nano generator is protected from external force, an electrical signal output is generated. The conventional piezoelectric composite film is prepared directly in the preparation of the flexible matrix and piezoelectric ceramic particles filler. However, in the curing of this piezoelectric composite film, under the influence of gravity, most of the particles aggregate in the lower portion of the piezoelectric composite film, and considering that the piezoelectric generator is stimulated by external force, large Some stresses will be absorbed and consumed...
