Chirag Mevada

I work as a postdoctoral research fellow at Tampere University. My research focuses on synthesizing non-toxic, biodegradable, and environmentally friendly electroactive materials for next-generation printed energy storage devices.

Synthesizing, material characterization, electrochemical characterization, development of inks from electroactive materials, optimizing printing parameters, and fabricating devices using advanced printing technologies (such as additive manufacturing). Additionally, integrating these devices with energy harvesters and sensors to test the applications of fully biodegradable printed energy storage devices. My main responsibilities also include writing manuscripts, communicating with partners to demonstrate fabricated devices, and providing reports as part of project work.

Synthesis of non toxic, biodegradable, and environmentally friendly electroactive materials (e.g., nanoparticles, porous materials, thin films, composites) for next-generation printed energy storage devices, including supercapacitors and batteries.

Establish a new paradigm for biodegradable energy storage for the next generation of sustainable printed electronics.
