Abstract

The project comprises of my study on the footstep power generation using piezoelectric sensor. The piezoelectric sensor is able to convert the kinetic energy into electrical energy. The kinetic energy can be obtained from human activities such as walking, running or others. In this project, I have done the research of piezoelectric sensor which uses the piezoelectric effect, to measure changes in pressure, force or others by converting them to an electrical charge. Next, when the piezoelectric sensor is being pressed, bended and stepped, it will convert the energy into electric charges and these charges are stored into a battery. In addition, the PIC microcontroller is able to read the charging voltage which the electric charges is temporarily stored in capacitor and rechargeable battery voltage by using the Analog-to-Digital converter (ADC). The PIC16F877A has 10-bit ADC which converts the signal results in corresponding 10-bit digital number. Then the value of the charging voltage and rechargeable battery voltage are displayed in the LCD. Furthermore, the battery may use to supply for lighting, mobile phone charging or others. The purpose of implementing the footstep power generation is to provide a temporary power supply during power trip. So it is very suitable to be implemented at crowded area such as LRT station, shopping mall, college and others.
