But the best compounds
for piezoelectricity are lead - based, and lead is something we all want to see phased out of electronics.
We're mostly familiar
with piezoelectricity when it comes to concept devices - things that can generate a charge based on pressure being applied to them.
The reason for graphene nitride's
unexpected piezoelectricity was predicted by Sharma in some of his earlier theoretical work on the topic.
The rubbery surface allows the applied mechanical stress of footsteps to produce piezoelectricity
One way would involve stringing quartz crystals, which can transfer electricity
via piezoelectricity, underground along known fault lines.
Gadget makers often rely
on piezoelectricity — the ability that some solids have to produce voltage when pressure is applied to them — to power tiny embedded systems, such as a BlackBerry Storm 2's touch screen or a car's airbag sensor.

Harnessing Piezoelectricity to Measure Earthquake Activity
According to Mocoloco, «The self - heating Piezo Shower
uses piezoelectricity, fibers that generate electricity through movement and friction, to heat water that flows through its many pipes.
The nanotechnology
for piezoelectricity is still under development and while designers are eager to incorporate it into products, we've yet to see how efficient it can really be.
Another unique factor about graphene nitride's
piezoelectricity is that the material can be stacked on top of itself — one atomic layer on top of another — without losing its piezoelectricity.
Most other atomically thin materials with piezoelectric properties don't maintain
their piezoelectricity when stacked, Zelisko said.
Traditional perovskites are typically metal - oxide materials that display a wide range of fascinating electromagnetic properties, including ferroelectricity and
piezoelectricity, superconductivity and colossal magnetoresistance.
Piezoelectricity is a hot area of research, with the self - charging materials being used to harvest energy from everything from insects to human joints.
Piezoelectricity is a result of a displacement of the charge distribution in the material due to deformation, and can be found in biological materials such as bone, protein and DNA and also in other types of materials such as ceramics, plastics and textiles.
First reported in the late fifties, this was initially attributed to
the piezoelectricity of bone's organic component, collagen.
The principle of
piezoelectricity describes the capacity of certain materials to deform upon the application of an electrical current and to return to their original state when the current is removed.
The researchers said they were surprised with just how powerful
the piezoelectricity of a fish scale is.
