Biodegradable generator turns air moisture into electricity

Capitals, May 26 (SANA) Researchers from British and Italian universities have developed a biodegradable generator that produces electricity from air humidity using simple materials such as gelatin, salt and activated carbon, in what could mark a significant step forward for sustainable electronics.

According to the US-based science and technology website Interesting Engineering, the device was developed by researchers from Queen Mary University of London, the University of Warwick, Imperial College London and Mercatorum University in Italy.

The generator converts moisture from surrounding air and human skin into electrical energy without the need for conventional batteries, complex components or non-degradable polymers, making it a more environmentally friendly alternative for low-power electronic devices.

Researchers said a single unit can generate electricity continuously for more than a month by absorbing moisture from the air. They added that connecting multiple units together could provide enough power to operate dozens of low-energy lights.

The device can also function as a flexible biosensor compatible with human skin. It is capable of monitoring breathing patterns, analysing speech through humidity changes in exhaled air and detecting nearby objects without direct contact.

Unlike traditional electronic devices, the generator can biodegrade in soil within weeks or dissolve in water, allowing its materials to be recycled more easily and helping reduce growing levels of electronic waste worldwide.

Researchers described the development as a promising step toward sustainable and low-cost energy technologies based on biodegradable natural materials.
