Electricity from Air Humidity: This technology is called Moisture-Electric Generator i.e. MEG. While common electronic devices get damaged due to humidity, this new system makes humidity its power.

(Now electricity will be generated from air moisture)

Electricity from Air Humidity: Amidst the growing e-waste and pollution worldwide, scientists have developed a new technology that can generate electricity from moisture in the air. Remarkably, this device is completely biodegradable and uses common materials that are also used in food and drink.

This research was conducted jointly by scientists from Queen Mary University of London, the University of Warwick, Imperial College London, and Universitas Mercatorum. This research has been published in the journal Nano Energy.

What is this new technology?

This technology is called Moisture-Electric Generator ( MEG) . While typical electronic devices are damaged by moisture, this new system harnesses moisture as its power. The device is made from inexpensive and safe materials like gelatin, common salt, and activated carbon. The manufacturing process is also very simple and water-based, which can significantly reduce production costs.

How is electricity produced?

This device absorbs moisture from the air or skin. When the gelatin and salt mixture dries, it forms a unique three-layer structure. Once it comes into contact with moisture again, the ions inside activate and begin to move. This process generates continuous electricity. According to scientists, a small unit can generate approximately 1 volt of electricity continuously for more than 30 days.

Can also run small appliances

The researchers combined multiple units to create a larger system. This setup generated up to 90 volts of power, enough to power small electronic devices and LED light strings. This suggests that this technology could become a battery-friendly alternative for small gadgets and sensor devices in the future.

Can also detect breath and body moisture

This technology isn't limited to generating electricity. Scientists have found that the device can also function as a sensor. Because its power output varies with humidity levels, it can detect even the slightest traces of moisture emitted from the human body. During their research, scientists used it to monitor breathing and measure moisture emitted during speech. In the future, it could be used in health monitoring devices, wearable technology, and touchless sensor systems.

Safe for the environment too

The device's biggest advantage is its environmental friendliness. While typical electronic products contain plastic, toxic chemicals, and heavy metals, MEG is designed to dissolve easily in the soil after use. It can degrade naturally within a few weeks, or its materials can be dissolved in water and reused. This is why scientists consider it a major step towards circular electronics.

This discovery could change the future of electronics.

Researchers believe that in the future, the reliance on rare and environmentally harmful materials to manufacture electronic devices may decrease. This new discovery shows that simple, inexpensive, and sustainable materials can be used to create high-performance technology that works in harmony with nature.
