Low powered hybrid piezolectric and termal energy harvester applications

Nowadays, technology is developing day by day along with great innovations in the field of energy as it is in every field. The energy consumption is increasing in the same direction as the developed technology. However, with the fast developing technology, the large amount of energy consumption has led to find the new search for new energy sources and has caused researchers to different areas and different solutions. Especially, the human body has been issued as a source of human energy to generate feasible power from heat dissipation, joint movements and even elastic deformations of tissues. The energy combinations obtained from daily activities allow the energy required to power the medical devices that can be used for a long time or permanently recharged and implanted. The thermal and mechanical energy analyzed in detail as well as the discussed in the literature as "Human-powered Based Energy Harvesting", and emphasis has been highlighted of the importance in the thesis.If we want to give an brief about the reseaches which were done by researchers, with only usage of piezoelectric materials which Works about the transformation of the mechanical energy to electrical energy was applied on the wearable healthcare monitoring systems, energy harvesting from shoes, energy harvesting from road, MEMS applications etc. Additionally, piezoelectric harvesters are commonly combined and applied with electromagnetic,thermal,magnetic and renewable energies. In the thesis, the studies are issued mainly Human-Powered Energy Harvesting with piezoelectricity and thermoelecticity. Briefly, thermal energy is based on body heat while mechanical energy is usually based on application and motion stimulation. Therefore, in the work mentioned above, the human energy is harvesting by implemention of by the help of thermoelectric generators from the body heat and then the mechanical force and the movement by the help of piezoelectric materials which can directly convert heat and mechanical energy to the electricity. It examplies how to store the hybrid energy stored in a battery and
