Abstract—with the increasing demand for utilization of energy resources, there has been a deflation in the availability of resources and there have been many methods of recycling of energy resources .It is our responsibility to ensure that we do not deplete all the energy resources leaving our future generations facing dangerous hazards. Our paper is one such attempt to reduce that burden. The method being employed by us is a new concept, which not only utilizes the principle of piezoelectricity to harvest energy but it also employs pyroelectric crystals and microcontroller to create a kind of feedback, with a battery getting charged automatically ,till it becomes fully charged. With piezo electric crystals it is possible to harvest energy from vibrating structures. Pyroelectric effect occurs when change in temperature causes flow of charges. These two effects are used to charge the various components being used in this experiment while remaining energy is being used to charge the battery. Our model aims to create a cyclic flow of energy, thus ensuring very less or no wastage of energy.

Index Terms—Microcontroller, piezoelectricity, pyroelectric effect.
