Among the many kinds of flexible devices, self-powered electronic systems have attracted great interest because they allow for sustainable, long-lasting and remote use of the device without additional energy storage systems. Among them, flexible piezoelectric energy harvesting technology that converts mechanical energy into electric energy have attracted interest. Conventional plastic substrate harvesters showed the possibility of piezoelectric energy generation from repeated deformation and small bending deformation, but due to complicated manufacturing process and size limitations, complex process and size limitations result in the commercialization of piezoelectric self-driving technology. This study is based on a hybrid film of BaTiO3 and resin, and consists of a simple and easy inkjet process. The flexible, large-area piezoelectric hybrid film and Ag electrode layers are printed on flexible prints with only non-contact inkjet processes without high temperature annealing and complex transfer processes. The morphology of hybrid film was analyzed by SEM. The crystallinity of BaTiO3 was confirmed by XRD and Raman spectroscopy. And the All-inkjet-printed energy harvester converts periodically to mechanical deformations into voltage. |
