AbstractResearch on green energy has been increasing tremendously in the past few years. Energy harvesting from an industrial pipeline conveying fluid using a hybrid harvester consisting of a piezoelectric beam and electromagnetic mechanism is proposed in this research thesis. Accumulated harvested energy can be stored over time utilizing an external battery to power smart sensing applications in remote locations. Existing harvesters in terms of piezoelectric or electromagnetic parts aim to obtain peak power by tuning techniques in terms of frequency, resistance or by manipulating fluid velocity. To address this nut, a hybrid harvester is proposed to acquire energy at stabilization cycles over unlimited time, providing a steady voltage based on realized 3D simulation in agreement with piezoelectric control algorithm and (EM) governing equation. The study covers water velocities from 0.34 to 1.36 m/sec when lift and transverse fluidforces reveal that water velocity of 1.36 m/sec and new originated velocity of 1.39 m/sec obtained by iteration could have further investigations. For the piezoelectric part,the mean voltages are 37.6 mV and 41.4 mV for water velocity of 1.36 m/sec and 1.39 m/sec, respectively, while mean voltages are 49.7 V and 91.8 V for water velocity of 1.36 m/sec and 1.39 m/sec respectively from the electromagnetic part
