 Area of Research Work 

 

1.  Energy  Harvesting  by Nanomaterials 

 Our research group focuses on energy harvesting by Nanomaterials.  From the last decade, most of the research work has been focused on sustainable and renewable energy sources such as solar, chemical, mechanical, thermal, wind, wave power energy, and also technologies designed to improve energy conversion efficiency. In addition to the above, the availability of fossil fuels is limited and their usage produces the CO2 and other gases into the atmosphere results in global warming.  Therefore, there is a need for producing clean, renewable and environmentally friendly alternate energy sources.  

Currently, we are working on piezo and pyroelectric nanogenerators based nanostructures for harvesting mechanical and heat energy respectively. The output power of these nanogenerators is useful to power up the small electronic devices, components,  circuits, sensors.
