Have you ever marveled at the seamless operation of a touch-sensitive screen or contemplated the intricacies behind the functioning of certain medical devices? Perhaps you’ve pondered the technology that allows some speakers to produce sound with remarkable precision. The answer to all these intriguing questions lies in a phenomenon called the piezoelectric effect.\u00a0<\/span><\/p>\n

This remarkable property, found in specific materials, allows them to generate electric charge in response to mechanical stress and vice versa. It’s a silent force that ensures the smooth operation of Piezoelectric motors, microphones, and some other actuators in consumer electronics like printers, etc.\u00a0<\/span><\/p>\n

Let’s learn about the piezoelectric effect, its causes, types, applications, and more!<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

What is the Piezoelectric Effect?<\/b><\/span><\/h2>\n

The piezoelectric effect is also known as Piezoelectricity and originates from the Greek word “Piezo,” meaning to push or to put pressure. It’s a phenomenon where the application of mechanical stress to a crystal or piezoelectric material induces the generation of voltage along its sides.\u00a0<\/span><\/p>\n

If an object is Piezoelectric, it means it has the ability to change the mechanical stress applied to it into electricity. Due to this unique characteristic, the piezoelectric effect makes it possible to implement renewable and sustainable energy in buildings through power harvesting and self-sustained smart sensing. <\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

Piezoelectric Effect Equation<\/b><\/p>\n

The principal equation governing piezoelectricity is given by:\u00a0<\/span><\/p>\n

P = d <\/b>x stress<\/b><\/p>\n

Where d represents the piezoelectric coefficient, a material-specific factor. For quartz, the piezoelectric coefficient is 3 x 10^-12, while for lead zirconate titanate (PZT), it is 3 x 10^-10. <\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

History of Piezoelectric Effect<\/b><\/span><\/h2>\n

In 1880, brothers Pierre Curie and Jacques Curie were working together when they came across a surprising phenomenon. They discovered that applying pressure to quartz – a Piezoelectric material – results in electric charge generation. This shift of mechanical energy into electrical energy is the basis of the piezoelectric effect or direct piezoelectric effect.\u00a0<\/span><\/p>\n

However, the discoveries didn’t stop there! Gabriel Lippman, in 1881, via mathematical deduction from fundamental thermodynamic principles, predicted an effect that’s opposite to the direct Piezoelectric Effect. He found out that applying electrical charge to a material causes the production of mechanical strain. This was also further elaborated by the Curie brothers.\u00a0<\/span><\/p>\n

These discoveries by Gabriel Lippman and Curies further ignited the interest of the European scientific community. This phenomenon became a field of research in the last quarter of the 19th century, and the first application of this effect was SONAR. It was developed in France in World War I. <\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>
