Abstract
A generator includes a sliding member, a first power generation element and a second power generation element. The sliding member is made of a biomass-containing material. The first power generation element is configured to slide with respect to the sliding member. The second power generation element is configured to generate electrical power by variation of its relative position with respect to the first power generation element.
Claims12
A generator, comprising:
- a sliding member having a cylindrical shape and made of a biomass-containing material;
- a first power generation element configured to slide across an interior surface of the sliding member;
- a second power generation element configured to generate electrical power in accordance with a variation of a relative position of the second power generation element with respect to the first power generation element, wherein at least a portion of the sliding member is located within the second power generation element;
- a casing made of a biomass-containing material, wherein the casing is configured to accommodate the sliding member, the first power generation element and the second power generation element;
- a fixing member made of an elastic material, wherein the fixing member contacts an inner surface of the casing and is configured to fix the second power generation element to the sliding member and to fix the sliding member to the casing via the elasticity of the fixing member;
- and
- a circuit board electrically coupled to the second power generation element.

A generator, comprising:
- a sliding member having a double cylinder shape with an inner peripheral space and an outer peripheral space, wherein the sliding member is made of a biomass-containing material;
- a first power generation element located in the outer peripheral space of the sliding member, wherein the first power generation element is not fixed to the sliding member and is configured to slide inside the sliding member while in contact with the sliding member;
- and
- a second power generation element located in the inner peripheral space of the sliding member, wherein the second power generation element is not fixed to the sliding member and is configured to slide inside the sliding member and generate electrical power in accordance with a variation of a relative position of the second power generation element with respect to the first power generation element.
