ABSTRACT. This paper discusses the use of piezoelectric material to generate electricity. This includes the basic theoretical modelling of the electrical power generation mechanisms and optimization of the piezo-host system. It is shown that with proper configuration, a single piezo-film can generate enough electrical density that can be stored in a rechargeable battery for later usage. KEYWORDS. Piezoelectric effects, Renewable energy, Vibration, Euler-Bernoulli, Power generator.
INTRODUCTION The recent fluctuations on the price of petroleum have affected worldwide economics which has forced an increased in the price of other items including food. Some even linked the recent collapse of few financial institutions in countries such US and the UK to the recent increased in this price. This shows that we are too dependent to petroleum as a source of electrical power. Besides, petroleum as a source of electrical energy has contributed to severe air pollution problem. Therefore, an alternative method to produced electricity has to be put in place. Among other solutions which can be explored are nuclear and hydroelectric power generators. However, these options require huge financial capability to run and to maintain. Besides, not many countries are “allowed” to use nuclear power generator due to world political scenario. Thus, photovoltaic cells and wind turbines have been the popular choices and these renewable energy sources
