Abstract:
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.

A product including a package is provided. One or more tobacco-containing articles may be received in the package. A power producer may be configured to produce an electrical current. An output mechanism may be configured to receive the electrical current from the power producer and output a perceptible effect. The perceptible effect may, for example, increase a consumer's interest in the product. A related method is also provided.
Abstract:
A generator includes a disc shaped first unit, a disc shaped second unit and an axle. The first unit includes a substrate layer, a double complementary electrode layer and an electrification material layer. The electrode layer includes a first electrode member and a second electrode member. The first electrode member includes evenly spaced apart first electrode legs extending inwardly. The second electrode member is complementary in shape to the first electrode member. The legs of the first electrode member and the second electrode member are interleaved with each other and define a continuous gap therebetween. The electrification material includes a first material that is in a first position on the triboelectric series. The second unit defines elongated openings and corresponding elongated leg portions, and includes a second material that is at a second position on a triboelectric series, different than the first position.

An energy harvester is provided. The energy harvester includes a first friction member, and a second friction member arranged to face the first friction member and generating electrical energy by causing friction with the first friction member. At least one of the first friction member and the second friction member includes a pyroelectric material converting frictional heat generated due to friction of the first and second friction members into electrical energy. While the energy harvester generates electrical energy by triboelectrification, the energy harvester may convert frictional heat into electrical energy by using a pyroelectric material.

An energy collection system may collect and use the energy generated by an electric field. Collection fibers are suspended from a support system. The support system is electrically connected to a load by a connecting wire. The collection fibers may be made of any conducting material, but graphene, carbon and graphite are preferred. Diodes may be used to restrict the backflow or loss of energy.

Abstract:
The disclosure discloses a vibration generator and a stacked-structure generator. The vibration generator includes an arched friction unit 1 and an arched friction unit 2. An concave inner surface of the arched friction unit 1 and an concave inner surface of the arched friction unit 2 are located opposite to each other as friction surfaces; and, the arched friction units 1 and 2 are provided with electrodes at convex outer surfaces thereof, which are concurrently served as supporting layers. The stacked-structure generator includes a plurality of the vibration generators, and several sets of a first geometrically complementary-shaped friction unit, which matches the electrode of the vibration generator that is concurrently served as the supporting layer, and a second geometrically complementary-shaped friction unit. The first geometrically complementary-shaped friction unit and the electrode concurrently served as the supporting layer that is coupled thereto and the second geometrically complementary-shaped friction unit and the electrode concurrently served as the supporting layer that is coupled thereto are attached to form a vibration generator that is complementary to the vibration generator. The present disclosure greatly increases output voltage of the generator and effectively increases collection and usage of environment energy.
