A SELF-POWERED BLUETOOTH NETWORK FOR INTELLIGENT TRAFFIC LIGHT JUNCTION MANAGEMENT

The purpose of this project is to model an energy harvester based on piezoelectric material. A cantilever beam type of piezoelectric is used for this project. The goal of the project is to power up a Bluetooth sensor. The simulation of piezoelectric is done using Simulink from basic mathematical model of piezoelectric. An energy harvester prototype is built in order to validate the power generation of the harvester. For the first testing, the result obtained is relatively low. After second testing, the result show the improvement from 0.077 volts to 5.6 volts.
