Scientists are inspired by tears to develop new materials that can be freely deformed

According to reports from international media, a team of bionic engineers at Harvard's Wyss Institute has drawn inspiration from tears to create a new type of deformable material capable of changing its transparency and texture on demand. This breakthrough could revolutionize the way we think about smart materials in various industries.

The researchers explained that when the material is stretched or physically altered, a continuous layer of liquid is injected into a nanoporous elastic substrate. This process allows the material to change its properties dynamically. By applying external force, the size of the nanopores within the material can be adjusted, which in turn affects the surface structure of the liquid-filled layer, enabling it to deform as needed.

Unlike traditional materials, which typically have either hydrophobic or hydrophilic surfaces, this new material mimics the natural behavior of a pitcher plant. It features a porous, liquid-filled, and smooth surface that can switch between different states. The ability to control pore size makes it possible to adjust the material’s flexibility and responsiveness, much like how tears help protect the eyes from foreign particles.

The research team is currently exploring ways to expand the material’s applications beyond just mechanical deformation. They hope to integrate it with light, temperature, magnetic fields, and electrical signals, making it even more versatile. In the future, this technology could be used in smart buildings, adaptive clothing, and medical devices, offering a wide range of practical benefits.

This innovative approach not only highlights the power of biomimicry but also opens up exciting possibilities for the next generation of responsive materials. As scientists continue to refine their techniques, the potential uses for such materials seem limitless.

Reverse Osmosis Plunger Pump

The special pumps in the Botuo Stainless Steel series are high-pressure with an 250 Bar to 1500 Bar 21-400 Litre stainless steel head. They are ideal for use in the food, chemical and pharmaceutical industries. The special pumps in the Botuo Stainless Steel series, stainless steel pressure washer pump, are also used in reverse osmosis systems, a procedure for purifying water used in particular in the food industry because it is able to remove pollutant particles from water without altering the mineral sources that are of particular importance for the body. Stainless steel is used as the main component because it is particularly corrosion resistant, and the inside has oversized tapered roller bearings able to guarantee longer duration. All the pump models produced by Leuco are renowned worldwide for their efficiency and reliability and the high quality of the materials used. botuo pumps also offers an efficient customer service able to provide all kinds of assistance and clarification.
