Working, Pros & Cons of Piezoelectricity – Something Worth Learning!
Piezoelectricity –
The term gives hint of buzzer device, right? Well, not necessary, it is more
than only use of device. The thing is, no explanation of piezoelectric effect
would be complete until and unless we don’t uncover for what other work the
piezoelectric devices are applicable to.
A big thanks to
incredible development of piezoelectric manufacturers who provide us an immense variety of products using
piezoelectricity apart from buzzers. Here, you can imagine how the rise of piezoelectricity
in electronic devices is growing at high scale.
Hey, wait, do you even know what piezoelectric means and how
Piezoelectric Material Works? Here we go;
What Does Piezo Mean & How does Piezoelectric Material Work?
The term “piezo” has been derived from an ancient Greek, according
to which it indicate an action of squeezing, pushing, and pressing.
The piezoelectric effect on other hand is an ability of specific
materials (like tourmaline, quartz, topaz and Rochelle salt etc.) to produce an
electric charge when exposed to mechanical stress.
How Piezoelectric Effect Works With Sensors and Motors?
There cannot be any other notable feature of piezoelectric
effect than being a high voltage power source in common electronic products
such as; cigarette lighters and gas grills. In these cases, a sledge strikes a
bit of piezo material, which at that point delivers enough current to make a
sparkle that touches off the combustible gas in its essence
If we look at other
such sensor applications, the hammer (the piezo material exciter) is normally
replaced by other forms of energy like sound waves — including ultrasound
Whereas, if they’re put to work in sensors, then piezo
materials are able to detect even the minute disturbances and anomalies, this
makes it an ideal devices in medical imaging, and an industrial nondestructive
testing
And, piezoelectric engines can perform profoundly exact and
repeatable developments. This capacity makes them superb gadgets for the
exactness developments of delicate optical gadgets like telescopes and
magnifying lens.
Advantages & Disadvantages of Piezoelectric Effect / Material
Like every product, piezoelectric devices also has few pros
and cons;
Advantages
· You don’t need any external power source: The
piezoelectric material is able to produce a voltage to act when force is
applied on it, piezo materials require no external power source
·
Stress-free
installation: Since it has small dimensions, so it easy to fit and install
in high-density electronic devices
·
Responsive
to high-frequencies: Unlike other devices, piezo material is substantially responsive
to higher frequency. This makes it wonderfully responsive in even the most
demanding situations
·
Highly
flexible: Larger part of piezo materials can be built in a wide assortment
of shapes and sizes, thus, they are exceptionally helpful for different
applications and fields.
Disadvantages
·
Small
measure of electric charge: Though they're self-creating, piezo materials
produce genuinely little electric charges, which implies a high impedance link
is required to associate them to an electrical interface
·
Environmental
conditions influence execution: Piezo materials are influenced by temperature
and changes in moistness. In addition, while in the static condition, they
can't quantify yield
