Abstract
A triboelectric generator includes a ferroelectric material layer and a protective layer provided over the ferroelectric material layer including first and second electrodes that are spaced apart from each other, a polarized ferroelectric material layer provided over the first electrode and configured to generate electrical energy by contact with another material, and a protective layer provided over the ferroelectric layer to prevent diffusion of charges generated on the ferroelectric layer.
Claims15
A triboelectric generator comprising:
- a first electrode and a second electrode, the first and second electrodes being spaced apart from each other;
- a polarized ferroelectric material layer over the first electrode;
- and
- a protective layer being spaced apart from the first electrode with the ferroelectric material layer interposed therebetween, the protective layer comprising hexagonal-boron nitride (h-BN) and configured to trap charges generated on the ferroelectric material layer to prevent the charges from diffusing to the outside, wherein
- the second electrode is configured to repeat a contact state and a non-contact state with the protective layer, and
- the ferroelectric material layer is configured to generate electricity by a separation between the protective layer and the second electrode, the separation caused by a transition from the contact state to the non-contact state.
A triboelectric generator comprising:
- a first electrode and a second electrode, the first and second electrodes being spaced apart from each other, and including at least one of carbon nanotubes (CNTs), graphene, and silver (Ag) nanowires;
- a polarized ferroelectric material layer over the first electrode and configured to generate electrical energy by contact with another material, the ferroelectric material layer comprising PVDF-trifluoroethylene (TrFE);
- a protective layer being spaced apart from the first electrode with the ferroelectric material layer interposed therebetween, the protective layer comprising hexagonal-boron nitride (h-BN) and configured to trap charges generated on the ferroelectric material layer to prevent the charges from diffusing to the outside;
- and
- a triboelectric charging layer under the second electrode.
