Tunable Transparency And Wettability: New Adaptive Material Inspired By Tears

Tunable Transparency And Wettability: New Adaptive Material Inspired By Tears:
Researchers have designed a new kind of adaptive material with tunable transparency and wettability features - imagine a tent that blocks light on a dry and sunny day, and becomes transparent and water-repellent on a dim, rainy day. Or highly precise, self-adjusting contact lenses that also clean themselves.
The new material was inspired by natural dynamic, self-restoring systems, such as the liquid film that coats your eyes - tears. Individual tears join up to form a dynamic liquid film with an obviously significant optical function that maintains clarity, while keeping the eye moist, protecting it against dust and bacteria, and helping to transport away any wastes – doing all of this and more in literally the blink of an eye.
