From moisture to electricity: Scientists show off how kitchen items can power wearables and smart home devices
Scientists at Queen Mary University of London have developed a device that converts ambient moisture into electricity. The Moisture-Electric Generator (MEG) utilizes common kitchen ingredients like gelatin, table salt, and activated charcoal. This innovative technology could potentially power wearables and smart home devices by harnessing humidity from the air or human skin.
- ▪The Moisture-Electric Generator (MEG) turns moisture into usable electricity.
- ▪It is made from gelatin, table salt, and activated charcoal, all of which are common kitchen items.
- ▪The device absorbs water molecules from the air or skin and separates into layers as it dries.

Opening excerpt (first ~120 words) tap to expand
What if the humidity in the air around you could charge your fitness tracker or power your smart home sensors? That is exactly what an international research team led by scientists at Queen Mary University of London has achieved. Their new device, called a Moisture-Electric Generator or MEG, turns ambient moisture into usable electricity using just three ingredients you could find in any kitchen: gelatin, table salt, and activated charcoal. How does it work? Science Direct The MEG works by absorbing water molecules from the surrounding air or directly from human skin. When the gelatin and salt mixture dries, it naturally separates into three distinct layers without any complex manufacturing steps.
