Natural disasters such as hurricanes, floods frequently occurs in the world. The cause of the natural disasters that occurs due to global warming because of increasing of global greenhouse gas emissions. To prevent the global warming, lots of researchers are studying renewable energy area. In order to protect grobal warming, government is trying to reduce green gas emissions under "Low Carbon Green Growth Policy" and investing climiate-friendly industries such as renewable energy harvesting. Research team is developing a renewable energy system that harvests mechanical energy imparted to road from driving vehicles and generates it into renewable electricity. This paper presents the research results of size effect of the piezoelectric ceramic and connection of piezoelectric ceramics. Power characteristics of piezoelectric ceramic as function of experimental variables were measured and analyzed.
