Lizard inspires system to extract drinking water from dry soil

Scientists have developed a device that collects water from the soil and purifies it, mimicking a desert lizard. This animal uses microchannels in its skin and jaw movements to obtain liquid. The system replicates that mechanism and removes 95% of contaminants such as lead and arsenic, offering a potential source of drinking water for arid regions.

How the bioinspired purification system works 💧

The device uses a surface with microscopic channels that capture moisture from the soil through condensation. A pumping mechanism, similar to the lizard's jaw movement, transports the water to a low-cost filter. Laboratory tests show a significant reduction of heavy metals and bacteria. The system operates without electricity, using only temperature and pressure differences, making it viable in regions without infrastructure.

The lizard was right: we didn't need apps for water 🦎

While large companies sell filters that require WiFi connection and software updates, a lizard has been solving the problem for millions of years using its mouth and skin. Now, copying its method sounds like science fiction, but at least you won't have to pay a monthly subscription to drink water. Of course, the lizard doesn't offer a money-back guarantee.
