Triboelectric nanogenerators (TENG) are being studied for scavenging energy from ambient vibrations originating from human motion, water droplets, and wind. I work on the novel architectures of devices and emerging electrodes for flexible/textiles based TENGs for harvesting energy and self-powered sensing.

Combined effect of capillary forces and streaming potential can help in harvesting steady direct current from natural water evaporation. My efforts are to develop efficient devices for enhanced evaporation resulting to increased output energy.

Laser-mediated explosive synthesis and transfer (LEST) is a technique recently developed by our group that enables simultaneous synthesis and transfer of graphene-like material on any desired substrate. Further we showcase the potential of this method for one-step synthesis and transfer of graphene composites. We have demonstrated the deposition of graphene films on polymers, glasses, textiles and metals. 

2D materials : graphene, TMDs (MoS2, MoSe2, WS2, PtSe2) and heterostructures of 2D materials with other 1D/2D or 3D materials.

I extensively combine chemical, sol-gel and physical deposition techniques [like sputtering, evaporation, and plasma etching] along with CVD and laser-assisted growth to achieve novel synthesis routes for engineered materials for application in energy harvesting.
