“The #UMass Amherst team were surprised to find that the device, which comprised an array of microscopic tubes, or #nanowires, was producing an electrical signal regardless.

Each nanowire was less than one-thousandth the diameter of a human hair, wide enough that an airborne water molecule could enter, but so narrow it would bump around inside the tube. Each bump, the team realised, lent the material a small #charge, and as the frequency of bumps increased, one end of the tube became differently charged from the other. ‘So it’s really like a battery,’”

Wait till you read about how in ‘59 the properties of #Nitinol were discovered?

“One of the systems, nickel-titanium alloy, immediately exhibited considerably more [fatigue-, impact-, and heat-resistance] than the other eleven alloys. … In 1959 Buehler...named [this nickel-titanium alloy] NITINOL (Nickel Titanium Naval Ordnance Laboratory). That same year he made an observation about [NITINOL] that hinted at the extraordinary, but still undiscovered, property of Nitinol. I distinctly remember my very exciting discovery of the acoustic damping change with temperature change near room temperature.”

"Optical metamaterials, which are designed to manipulate light, possess structures with repeating patterns at scales that are smaller than the wavelengths of light they influence."

According to an article published in Nature, It may be possible to engineer buildings with foundations which reduce earthquake damage via the recent science of "metamaterials", or structures designed with carefully shaped patterns which can direct the flows of various forms of energy.
