Abstract
The present disclosure provides a flexible electric generator and methods for fabricating the same. The flexible electric generator comprises a flexible triboelectric layer covering the electrode layer of a flexible piezoelectric generator that enhances output power by combining piezoelectric effect and triboelectric effect. The reliability of the flexible electric generator under bending is also improved due to the presence of the flexible triboelectric layer. The fabrication methods of the disclosed flexible electric generators are simple, thereby enabling large-scale manufacturing.

An electric generator comprising:
- a piezoelectric generator comprising:
- a flexible piezoelectric layer for generating a first electric power via piezoelectric effect under contact between the electric generator and a first surface contact object and/or a second surface contact object;
- a first flexible dielectric layer having a bottom surface partially or fully covering a top surface of the flexible piezoelectric layer;
- a second flexible dielectric layer having a top surface partially or fully covering a bottom surface of the flexible piezoelectric layer;
- a first flexible electrode layer comprising a first covering portion having a bottom surface partially or fully covering a top surface of the first flexible dielectric layer;
- and
- a second flexible electrode layer comprising a second covering portion having a top surface partially or fully covering a bottom surface of the second flexible dielectric layer;
- a first flexible triboelectric layer having a bottom surface partially or fully covering a top surface of the first covering portion of the first flexible electrode layer for generating a second electric power via triboelectric effect under contact and separation between a top surface of the first flexible triboelectric layer and the first surface contact object;
- and
- a second flexible triboelectric layer having a top surface partially or fully covering a bottom surface of the second covering portion of the second flexible electrode layer for generating a third electric power via triboelectric effect under contact and separation between a bottom surface of the second flexible triboelectric layer and the second surface contact object.
