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

Output is generally low: While some piezo materials produce more yield than others, they're all moderately low. For their utilization to be upgraded, an outer circuit will frequently be required
