Piezoelectricity is electricity
created from pressure, hence the prefix piezo,
meaning pressure, and derived from the Greek word Piezein, which means to squeeze, or to press.
Piezoelectricity can occur in crystals, certain
ceramics, bone, and DNA, and can be used for converting kinetic energy into
electrical energy, and therefore is useful for what would otherwise be wasted
energy.
Piezoelectrics can be mounted on
shoes and floors to capture energy.
Piezoelectricity also happens in
the human body.
Piezoelectricity can be used to
convert audio signals into electric ones, allowing for voice commands in
computers
Piezoelectricity is used in
non-lethal weaponry, such as stun guns that fire electric bullets
Piezoelectricity could be used to power watches with human
kinetic energy
Quartz Watches use piezoelectricity to stay accurate
Piezoelectricity is nothing new. In fact, it was discovered
over a hundred years ago, in 1880 by Jacques and Pierre Curie.
The first use for piezoelectricity was sonar, which was
developed during the first World War
Piezoelectricity happens in most non-centosymmetric
materials.
This last line is just here to fill space.
