Moisture electric power generation (MEG) through the interaction between moisture and materials has been tested by several scientists. A research team to overcome the problem of device interruption caused by the absorption of saturated water created an ultra-thin, self-charging mechanism that generates electricity using moisture in the air.

This first-of-its-kind moisture-powered power generation (MEG) device was developed by a research team from the National University of Singapore (NUS) School of Design and Engineering. The rechargeable “battery” that uses sea salt as an environmentally friendly moisture absorber is actually just a fabric, but Provides more power than a traditional AA battery.

The development of MEG devices has received increasing attention in the real world due to a wide variety of potential applications in the field of so-called self-powered devices, meaning they do not need an external energy source to operate. . Among the best known are wearable electronics such as health monitors, skin sensors and data stores.

The main challenge the researchers faced was solving, in addition to water saturation, unsatisfactory and unsustainable electrical performance. With this in mind, the team built A MEG with two regions with different propertiesto maintain a permanent water content difference between the two sides, generating electricity and allowing hundreds of hours of output.

For this, they covered the wet area of ​​the tissue with a hygroscopic ionic hydrogel. made with sea saltThe gel can absorb more than six times its original weight value to collect moisture from the air. At the other end, the fabric is kept absolutely dry. Electricity is produced when the ions in the sea salt separate as the water is absorbed on the wet side.
