Abstract/Description:
Energy harvesting has become an important subject as in recent years, structures all around the world are reinforced with elements that consume energy. Sensors, actuators, such structural health monitoring devices are implemented vastly. In order to keep these devices running, electrical energy has been transferred through enormous endeavors. Especially in the remote areas this power distribution has been an important issue. In this research, the problem of providing energy to the small device has been addressed by introducing a novel piezoelectric energy harvester.

Many other researches have been done in this matter before. Mostly have been focusing on the vibrational behavior of the energy harvesting structure. In this research, the problem was faced with the assumption that there is very low frequency or even no vibration at all. Since in the nature, most of the external forces are applied as cyclic stresses. In this research by using this phenomenon, an energy harvester was developed. The energy harvester was designed initially using CAD and finally manufactured and tested using simple 3D printing. Since the energy harvesting is dependent on the piezoelectric element, deformation mechanism is the center of this research. Utilizing the concept of bistable structures and implementing the snap-through deformation the device designed to be capable of energy harvesting. he device was analyzed and proved to be feasible from the aspects of energy generation, charging, and quality of functionality in different situation. The structure is designed to be easily usable, readily implemented and as a periodic structure capable of expansion.
