Meghana Addanki: Electricity from Eggshell Membrane and Cotton
Electricity from Eggshell Membrane and Cotton.
Meghana Addanki fabricated a piezo-triboelectric hybrid generator using a zinc-oxide-modified eggshell membrane and cotton. The work explores low-cost biomaterials as active components in energy harvesting rather than treating them only as waste.
Innovation mindset: Before sourcing an exotic material, inspect everyday biological waste for useful structure and electrical behaviour.
Official project title: Efficient Energy Harvesting Using Biomaterials: Fabrication of a ZnO-Modified Eggshell Membrane and Cotton Based Piezo-Tribo Hybrid Generator (Energy: Sustainable Materials and Design).
