Triboelectric generator

A triboelectric generator comprising:

• first and second electrodes spaced apart from each other;
• a first charging object and a second charging object,
• the first charging object being on a surface of the first electrode facing the second electrode,
• the first charging object configured to be positively charged due to contact with the second charging object,
• the second charging object being between the first charging object and the second electrode, the second charging object configured to be negatively charged due to contact with the first charging object;
• and
• a grounding unit configured to intermittently interconnect the second charging object and a charge reservoir due to motion of the second charging object,
• wherein the first charging object contacts the surface of the first electrode, and
• the second charging object is configured to be spaced apart from the first charging object and the second electrode.
