A HYBRID PIEZOELECTRIC AND TRIBOELECTRIC NANOGENERATOR

摘要

A hybrid piezoelectric and triboelectric nanogenerator includes: a first superpolymer insulating layer (10); a first electrode (11), located on the surface of the first superpolymer insulating layer (10); a second superpolymer insulating layer (12); a second electrode (13), located on the surface of the second superpolymer insulating layer (12); an intermediate thin film (14), located between the first and the second superpolymer insulating layers; a first piezoelectric nanowire array (15), grown vertically on the first electrode (11); a third superpolymer insulating layer (16), covering the first piezoelectric nanowire array (15); a third electrode (17), located on the surface of the third superpolymer insulating layer (16), a second piezoelectric nanowire array (18), grown vertically on the second electrode (13); a fourth superpolymer insulating layer (19), covering the second piezoelectric nanowire array (18); and a fourth electrode (20), located on the surface of the fourth superpolymer insulating layer (19). The above nanogenerator can greatly improve the generating efficiency.
