Electricity is the main source of power for most of the country’s economic activities. Non-commercial energy sources, such as wood fuel, animal waste, and crop residues, are estimated to justify over half of the country’s energy consumption. Bangladesh has small stock of oil and coal, but very enormous natural gas resources. Piezo-element can generate electricity that can be stored in a rechargeable battery for later use. When people run and walk, a huge amount of pressure is being created. Therefore we use this concept that mechanical stress from pressure on the Piezo element produces some electrical energy which can be stored in a rechargeable battery and later this stored energy can be used to charge portable electronic devices. So if we can produce electricity just by walking or running which reduce the pressure on natural resources.. The increasing prevalence and portability of compact, low power electronics require reliable power sources. Compared to batteries, these devices show much potential as power sources.
