This project presents the development of power generation energy by using piezoelectricity effect.The wasted mechanical energy from walking can be converted to electrical energy by using a piezoelectric transducer and can be stored in a battery for later use.The main idea is to construct a power generation system, which includes the piezoelectric transducers as renewable sources that can be used to power up low power application.The piezoelectric transducers are able to produce electrical charges by stressed when subjected to dynamic strain (expand). Three circuits used to improve this project were voltage multiplier circuit, charge controller circuit, and LCD display DC voltage output circuit.Voltage Multiplier circuit was the main circuit that used to convert from AC main power supply generated from the piezoelectric sensor to DC supply as the output.The piezoelectric sensor regulated DC voltage output and charged the rechargeable battery.The basic Arduino coding was used to display DC voltage from the battery to easily know and predict the output voltage from the piezoelectric transducer to do the analysis.The 16 V maximum voltage already taken out from this piezoelectric circuit was enough to charge a 7.4 V rechargeable battery.
