<p>The present invention relates to an oscillation energy harvesting device, which can effectively harvest wasted energy to use the harvested energy as power of a device using low power and can be coupled to a periodic oscillation generator to perform efficient generation, and a power generation system using the same. The oscillation energy harvesting device can have various sizes, be used for various purposes, and have a long life at a relatively low cost by using a solid leaf spring, which elastically oscillates by a forced oscillation method using external power instead of an oscillation energy harvesting method using an expensive piezoelectric device with a high risk of damage due to direct impact transmission, to harvest energy from oscillation of the leaf spring. The oscillation energy harvesting device can induce resonance by adjusting the characteristics of the leaf spring according to external oscillation to match a unique frequency of the leaf spring with external energy, thereby improving efficiency by maximizing the amplitude of oscillation. As a result, configuration costs, installation costs, and management costs can be reduced and universality can be increased, thereby securing economical efficiency.</p> |
