Abstract
Official abstract text for this publication.
A generator includes a first member, a second member and a sliding mechanism. The first member includes a first electrode and a first dielectric layer affixed to the first electrode. The first dielectric layer includes a first material that has a first rating on a triboelectric series. The second member includes a second material that has a second rating on the triboelectric series that is different from the first rating. The second member includes a second electrode. The second member is disposed adjacent to the first dielectric layer so that the first dielectric layer is disposed between the first electrode and the second electrode. The sliding mechanism is configured to cause relative movement between the first member and the second member, thereby generating an electric potential imbalance between the first electrode and the second electrode.
First claim
Opening claim text (preview).
What is claimed is: 1. A generator, comprising: (a) a substantially cylindrical first member, including: (i) a first electrode; and (ii) a first dielectric layer affixed to the first electrode, the first dielectric layer including a first material that has a first rating on a triboelectric series, the first dielectric layer including a first grating of evenly spaced apart parallel ridges and troughs disposed along a second direction that is transverse to a first direction; (b) a substantially cylindrical second member disposed inside of the first member, the second member including a second material that has a second rating on the triboelectric series that is different from the first rating, the second member including a second electrode, the second member disposed adjacent to the first dielectric layer so that the first dielectric layer is disposed between the first electrode and the second electrode, the second member including a second grating of evenly spaced apart parallel ridges and troughs disposed along the second direction; and (c) a sliding mechanism configured to cause relative motion between the first member against the second member, thereby generating an electric potential imbalance between the first electrode and the second electrode, wherein the ridges and troughs of the first grating and the second grating extend parallel to a cylindrical axis and wherein the sliding mechanism is configured to cause relative rotational motion between the first member and the second member about the cylindrical axis. 2. The generator of claim 1 , wherein the ridges of the first grating have a nanoscale texture on an outer surface thereof. 3. A generator, comprising: (a) a substantially cylindrical first member, including: (i) a first electrode; and (ii) a first dielectric layer affixed to the first electrode, the first dielectric layer including a first material that has a first rating on a triboelectric series, the first dielectric layer including a first grating of evenly spaced apart parallel ridges and troughs disposed along a second direction that is transverse to a first direction; (b) a substantially cylindrical second member disposed inside of the first member, the second member including a second material that has a second rating on the triboelectric series that is different from the first rating, the second member including a second electrode, the second member disposed adjacent to the first dielectric layer so that the first dielectric layer is disposed between the first electrode and the second electrode, the second member including a second grating of evenly spaced apart parallel ridges and troughs disposed along the second direction; and (c) a sliding mechanism configured to cause relative motion between the first member against the second member, thereby generating an electric potential imbalance between the first electrode and the second electrode, wherein the ridges and troughs of the first grating and the second grating are disposed circumferentially so as to be transverse to a cylindrical axis and wherein the sliding mechanism is configured to cause reciprocating motion between the first member and the second member along the cylindrical axis. 4. The generator of claim 3 , wherein the ridges of the first grating have a nanoscale texture on an outer surface thereof. 5. A generator, comprising: (a) a substantially cylindrical first member, including: (i) a first electrode; and (ii) a first dielectric layer affixed to the first electrode, the first dielectric layer including a first material that has a first rating on a triboelectric series, the first dielectric layer including a first grating of evenly spaced apart parallel ridges and troughs disposed along a second direction that is transverse to a first direction; (b) a substantially cylindrical second member disposed inside of the first member, the second member including a second material that has a second rating on the triboelectric series that is different from the first rating, the second member including a second electrode, the second member disposed adjacent to the first dielectric layer so that the first dielectric layer is disposed between the first electrode and the second electrode, the second member including a second grating of evenly spaced apart parallel ridges and troughs disposed along the second direction; and (c) a sliding mechanism configured to cause relative motion between the first member against the second member, thereby generating an electric potential imbalance between the first electrode and the second electrode, wherein the ridges and troughs of the first grating are helically disposed about an inside surface of the first member and wherein the ridges and troughs of the first grating and the second grating are helically disposed about an outside surface of the second member. 6. The generator of claim 5 , wherein the ridges of the first grating have a nanoscale texture on an outer surface thereof.
