This research proposes a new concept of energy harvesting with the help of oscillating slugs of ferrofluid in microchannels. Ferrofluids are colloidal suspension of paramagnetic nanoparticles which get magnetized in the presence of magnetic field. They can conform to any shape and can be injected easily in intricate spaces. A change in the magnetic flux through the solenoid area produces electromotive force per Faraday’s law. To prove the concept of harvesting energy by having a change in magnetic flux with the help of ferrofluids, several ferrofluid slugs were made to pass through a multi turn solenoid wound around a glass micro channel with the help of a fluid dispensing pump. Various parameters affecting the generation of the electromotive force are studied with the help of numerical study. A comparison between the experimental data and the results of finite element analysis using COMSOL Software has also been done. With progress in development of different energy harvesting device, using microfluidics for energy scavenging is still a novel concept which has a wide scope for advancement. The applications of the device proposed in this research include low wind energy harvesting.
