Electronic wearables and sensors could one day be made from a material that toughens up as it gets hit or stretched, thanks to new research carried out by a team from the University of California, Merced.
This 'adaptive durability', as it's known, is an important characteristic in terms of the science of materials. It means protection against damage and resistance to stress, even in harsh environments.
The new material was actually inspired by the corn starch used in cooking, which can be stirred when water is added. Unlike wet sand, which has a consistent viscosity whether mixed or punched, cornstarch slurry acts like a liquid when stirred gently and like a solid when punched quickly.
When you squish cornstarch slowly, the tiny particles repel each other, making them act like a fluid. But if you hit the surface fast, they touch, causing friction and acting like a solid. This difference in behavior is due to the size of the particles.
The researchers wanted to see if they could get the same results from a polymer material.

It says right here in Matthew 16:4 "Jesus doth not need a giant Mecha."

Geez, this dude needs to learn to wear safety goggles for his experiments.

To everyone pointing out non-newtonian fluids, liquids are pretty hard to wear as clothing.

These guys are making a fabric/polymer of some sort with similar properties. That's the new part. It's a solid.
