Triboelectric generator

A triboelectric generator comprising:

• a first electrode;
• a first charging part on the first electrode, the first charging part having a first charging rating, the first charging part including a first material;
• a second electrode spaced apart from the first electrode;
• a second charging part configured to contact a surface of the first charging part through sliding motion,
• the second charging part being configured to contact a surface of the second electrode through sliding motion,
• the second charging part having a second charging rating that is different than the first charging rating,
• the second charging part including an electrically conductive material that is different than the first material;
• and
• a grounding unit configured to intermittently connect the second charging part to a charge reservoir according to movement of the second charging part.

A triboelectric generator comprising:

• a first electrode and a second electrode spaced apart from each other;
• a first charging part and a second charging part,
• the first charging part being on the first electrode,
• the first charging part being configured to be charged a first polarity due to contact with the second charging part,
• the second charging part being configured to slide on a surface of the first charging part,
• the second charging part being configured to be charged with a second polarity that is opposite to the first polarity through contact with the first charging part;
• and
• a grounding unit configured to intermittently connect the second charging part to a charge reservoir according to movement of the second charging part,
• wherein the grounding unit is between the first electrode and the second electrode,
• and the second charging part is configured to slide on an upper surface of the grounding unit.
